Abstract:
Disclosed is a fuel cell membrane electrode assembly (MEA) embodiment including an anode layer; at least one exchange membrane that is disposed on the anode layer as either a single-layered structure including one exchange membrane or a multi-layered structure including a plurality of exchange membranes, each exchange membrane of the at least one exchange membrane consisting of a film comprising hexagonal boron, and the at least one exchange membrane having a total thickness ranging from 0.3 to 3 nm; an interfacial binding layer that completely covers an exposed surface of one exchange membrane which is obverse to the anode layer and that consists of poly(methylmethacrylate) (PMMA) as a binder material; and a cathode layer formed on the interfacial binding layer. Alternately, a fuel cell membrane electrode embodiment may completely eliminate the interfacial binding layer and both embodiments provide superior fuel cell performance.
