- the filter media 25 of panel filter 15 ' and filter media 25 ' of tubular element 15" are selected for their capability for removing physical (e.g., particulate) contaminants, chemical contaminants, or both.
- a separate portion of the filter element can be used for the removal of each contaminant, or a single filter element can be used for the removal of multiple contaminants.
- a separate particulate filter portion is used for removing physical contaminants such as particulates and a chemical filter portion is used for removing chemical contaminants. This arrangement is preferred to maximize the efficiency of the chemical filter element by removing large particulates before they reach the chemical filter portion and potentially clog, block, or occlude the filter.

- Another example of a media for removing liquid contaminants is a media of treated glass fibers combined with foamed hot melt beads. These exemplary media can be incorporated into extensions of filter media, such as pleated paper extensions.
- the preferred technique for removing liquid contaminants is to use an inertial separator; this, however, can be dependent on the space available within the fuel cell apparatus.
- An expanded PTFE (polytetrafluoroethylene) membrane can also be used to remove liquid from the air. Expanded PTFE is a microporous membrane that, because of the pore size, allows the passage of moisture (vapor) through but not liquid.
- particulate filter portions having any combination of particulate removal efficiency can be used.
- the desired particulate removal system will depend on the type of contaminants present in the atmosphere (for example, leaves, cottonwood blossoms, lint, snow, etc.) and the desired cleanliness level of the resulting filtered air.

- the shaped adsorbent typically includes not less than about 2%, by weight, binder and not more than about 30%, by weight, binder. Further information regarding mold release, other additives, and molding techniques are discussed in U.S. Patent No. 5,876,487.
- a suitable adsorbent material for use in the chemical filter portion is an adsorbent material that includes a carrier.
- a mesh or scrim can be used to hold the adsorbent material and binder. Polyester and other suitable materials can be used as the mesh or scrim.
- any carrier is not more than about 50% of the weight of the adsorbent material, and is more often about 20 to 40% of the total adsorbent weight.

- basic compounds that are often present in atmospheric air include ammonia, amines, amides, sodium hydroxides, lithium hydroxides, potassium hydroxides, volatile organic bases and nonvolatile organic bases.
- the acidic and basic materials of the chemical filter portion remove contaminants from the air by trapping the contaminants on their surfaces; typically, the acidic and basic surfaces react with the contaminants, thus adsorbing the contaminants at least on the surfaces.
- the composition itself of the carrier may be the strongly acidic or strong basic material.
- the strongly acidic materials and the strongly basic materials can be provided as surface coatings on carriers such as granular particulate, beads, fibers, fine powders, nanotubes, and aerogels.
- the acidic and basic material that forms the acidic and basic surfaces may be present throughout at least a portion of the carrier; this can be done, for example, by impregnating the carrier material with the acidic or basic material.
- An example of a preferred material for removing basic contaminants, such as ammonia, is a bed of activated carbon granules impregnated with citric acid.
- An example of a preferred material for removing acidic contaminants is abed of impregnated activated carbon granules that are commercially available from C*Chem, a division of IONEX Research Corp. of Lafayette, CO, under the trade designation "Chemsorb 1202".
- Both basic and acidic materials may be present in the chemical filter portion of the filter element; however, it is preferable that the two types of materials are spaced from each other so that they do not react with and neutralize one another.

- the chemical filter portion removes chemical contaminants from the dirty air stream so that the filtered clean air has a contaminant concentration that is below, or at least at, an acceptable threshold before passing the air into the input of the equipment, such as the fuel cell.
- the contaminant level in the dirty air stream is below the threshold level, it is not necessary for the filter element to remove contaminants; rather, in some embodiments the chemical filter portion may release some of the collected contaminants, up to the threshold level. This is generally caused by the contaminate concentration differential between the dirty air stream and the chemical filter portion. In this way, the chemical portion may be partially regenerated, thereby extending the useful life of the chemical filter portion.
- Such a design may be desired when an acceptable threshold level of contaminants into the fuel cell is known.
- a particulate filter portion and chemical filter portion can be combined to provide a single filter element that removes both physical and chemical contaminants.
- the filter media of a particulate filter portion can be made with fibers that have a surface treatment capable of chemisorbing or otherwise reacting or interacting with acidic or basic contaminants, thus providing a chemical filter portion.
- a bed of activated carbon granules can also remove physical contaminants from the air if the spacing between the granules is sufficiently small.
- a by-pass system for by-passing the chemical filter portion. This may be desired in environments when the intake air is not highly contaminated with chemical contaminants. This by-pass system may be activated and deactivated, depending on the contaminant levels in the intake air stream.
- a first example of a preferred filter assembly is a filter assembly having both particulate and chemical filtration capabilities.
- the filter assembly has one layer of particulate media providing a physical filter portion and three layers of adsorptive media providing a chemical filter portion.

- one preferred filter assembly construction has a first layer of pleated glass media as a particulate filter positioned around two packaged granular carbon beds and a central electrostatic media.
- the particulate filter portion preferably has a pleated glass fiber media having a construction well known in the filter art. Beads of material, such as hot melt adhesive, can be used for pleat separation.

- Fuel cells are devices consisting of two electrodes (an anode and a cathode) that sandwich an electrolyte.
- a fuel containing hydrogen flows to the anode, where the hydrogen electrons are freed, leaving positively charged ions.
- the electrons travel through an external circuit which the ions diffuse through the electrolyte.
- the cathode the electrons combine with the hydrogen ions and oxygen to form water and carbon dioxide, byproducts.
- a catalyst is often used. Examples of catalysts often used in the fuel cell reaction include nickel, platinum, palladium, cobalt, cesium, neodymium, and other rare earth metals.
- the reactants in the fuel cell are the hydrogen fuel and an oxidizer.
- the fuel cell 102 for use with the filter assembly is known as a "low temperature fuel cell” because of its low operation temperature, typically about 70 to 90°C.
- High temperature fuel cells are also known, however, these are typically not as sensitive to chemical contamination due to their higher operating temperature. High temperature fuel cells are however sensitive to particulate contamination, and some forms of chemical contamination, and may benefit from the type of filtration system described herein.
- One type of low temperature fuel cell is commonly referred to as a "PEM”, is named for its use of a proton exchange membrane.
- PEM fuel cells will benefit by being used in conjunction with a filter assembly according to the present invention.
- Examples of other various types of fuel cells that can be used in combination with the filter assembly of the present invention include, for example, U.S. Patent Nos. 6,110,611; 6,117,579; 6,103,415; and 6,083,637. It will be recognized by one skilled in the art of fuel cells that the filter assembly will benefit the operation of generally any fuel cell.
- the threshold levels of contaminants that are acceptable by various fuel cells is dependent on the design of the fuel cell. For example, hydrocarbons (methane and heavier), ammonia, sulfur dioxide, carbon monoxide, silicones, and the like, are known to occupy space on the catalyst and inactivate the sites to reaction. Thus, these contaminants need to be removed prior to their entering the reactive area of the fuel cell. The exact level of contamination, and types contaminants that are acceptable will vary depending on the catalyst used, the operating conditions, and the catalytic process efficiency requirements.
- the filter assembly of the present invention removes contaminants from the atmospheric air before the air is used in the fuel cell operation.
