1. A planar configuration air breathing polymer electrolyte electrochemical device comprising:
a support plate; and at least two air breathing polymer electrolyte fuel cells arranged in series connection on one surface of the support plate, wherein each of said air breathing polymer electrolyte fuel cells comprises:
a. an anode current collector,b. a cathode current collector, andc. a membrane electrode assembly, which comprises a solid ion conducting polymer membrane electrolyte, an anode, an anode gas backing, a cathode and a cathode gas backing, and wherein: the support plate comprises at least three layers in a sandwich structure, the at least three layers comprise a first outer layer, a middle layer, and a second outer layer, the first outer layer forms a gas inlet, the second outer layer forms one or more gas openings, the middle layer forms one or more gas channels, the one or more gas openings formed by the second outer layer include:
a first-cell outlet configured to conduct fuel out of a first fuel cell of the at least two fuel cells, anda second-cell inlet configured to conduct fuel into a second fuel cell of the at least two fuel cells, and one of the one or more gas channels is configured to conduct fuel from the first-cell outlet to the second-cell inlet. |
