ABSTRACT:
A proton exchange membrane fuel cell has a unit cell assembly including an anode side and a cathode side. The anode side has a cooling base plate, a conductor assembly, a hydrogen flow field, a water absorbing element, and a hydrogen duct assembly. The cathode side has an air flow field, a conductor assembly, an air flow distributor, and an insulating compression plate with wing extensions. A membrane electrode assembly is disposed between the anode side and the cathode side physically connecting the flow fields on both the anode and cathode sides. A sealed anode assembly creates a sealed hydrogen volume and includes the anode conductor assembly, the hydrogen duct assembly, and the membrane electrode assembly all disposed between the insulating compression plate and the cooling base plate. The fuel cell may comprise multiple unit cell assemblies arranged in planar, folded, stacked, or pancake configurations.
