ABSTRACT:
A method for making fuel cells is disclosed and includes placing catalyst strips on an anode side and a cathode side of a proton exchange membrane disposed between carbon bases. The method includes metalizing at least two collectors, and drilling a plurality of paths through the body portions to form a first and second metalized collectors, which are placed on opposite sides of the proton exchange membrane to form a membrane electrode assembly. The metalized collectors are connected to form an electrical circuit for operating the fuel cell. A flexible fuel plenum and a flexible oxidant plenum are disposed on opposite sides of the membrane electrode assembly, and a fuel manifold and an oxidant manifold of a sealable two-part housing engage the membrane electrode assembly to provide oxidant to the flexible oxidant plenum and fuel to the flexible fuel plenum forming an operational singe unit fuel cell.
