Abstract
Disclosed is a polymer electrolyte membrane (PEM) fuel cell assembly apparatus for receiving an inserted membrane electrode assembly (MEA). The apparatus includes modular features for connecting a plurality of fuel cells into a planar fuel cell “stack” capable of using ambient air to supply oxidant gas and dissipate heat and water vapor. The invention also facilitates convenient removal and replacement of individual cells or MEAs in a stack without disassembly of the entire stack.
