Abstract

It is known per se that individual fuel cell units can be mechanically stacked on top of each other according to a predetermined stack length, whereupon they are electrically and fluidically connected in a successive manner. According to the invention, fluidic inertial forces are used to evenly distribute all media, especially the reactants, in the individual fuel cell units and are transferred in precise matching geometrical dimensions of distributing and/or reaction channels.
