Crown ether containing PEM electrode

摘要

A membrane electrode assembly for fuel cells includes a proton conducting membrane having a first side and a second side. The membrane electrode assembly further includes an anode disposed over the first side of the proton conducting layer and a cathode catalyst layer disposed over the second side of the proton conducting layer. One or both of the anode catalyst layer and the cathode catalyst layer includes a first polymer which has cyclic polyether groups. An ink composition for forming a fuel cell catalyst layer is also provided.

1. A membrane electrode assembly for a fuel cell, the membrane electrode assembly comprising:
a proton conducting membrane having a first side and a second side; an anode catalyst layer disposed over the first side of the proton conducting layer; and a cathode catalyst layer disposed over the second side of the proton conducting layer, at least one of the anode layer or the cathode layer including a first polymer including cyclic polyether groups and platinum, the platinum being sequestered by the cyclic polyether groups, the membrane electrode positioned between a first gas diffusion layer and a second gas diffusion layer and between an anode flow field plate and a cathode flow field plate.
