ABSTRACT:
The invention relates to a portable electrical energy generator, its components, and manufacture of the components and generator. The generator includes a bi-polar plate stack, which is well suited for use in a fuel cell. The stack may include at least one spacer that limits compression of a membrane electrode assembly in the fuel cell. The stack may also include a polymer binder that holds the stack together and/or maintains a compression force on the membrane electrode assembly. An open cathode manifold may also provided to ease oxygen movement. High throughput and low cost manufacture of bi-polar plates is also described herein.
