Solid polymer electrolyte composite membrane comprising a porous support and a solid polymer electrolyte including a dispersed reduced noble metal or noble metal oxide

摘要

A solid polymer electrolyte composite membrane and method of manufacturing the same. According to one embodiment, the composite membrane comprises a thin, rigid, dimensionally-stable, non-electrically-conducting support, the support having a plurality of cylindrical, straight-through pores extending perpendicularly between opposing top and bottom surfaces of the support. The pores are unevenly distributed, with some or no pores located along the periphery and more pores located centrally. The pores are completely filled with a solid polymer electrolyte, the solid polymer electrolyte including a dispersed reduced noble metal or noble metal oxide. The solid polymer electrolyte may also be deposited over the top and/or bottom surfaces of the support.

1. A solid polymer electrolyte composite membrane, said solid polymer electrolyte composite membrane comprising:
(a) a first non-electrically-conductive support, said first non-electrically-conductive support having opposing top and bottom surfaces, a plurality of pores being provided in said first non-electrically-conductive support, said pores extending directly from said top surface to said bottom surface, wherein said pores are unevenly distributed in said first non-electrically-conductive support, with at least some of said pores being located in a peripheral portion of said first non-electrically-conductive support and at least some of said pores being located in a non-peripheral portion of said first non-electrically-conductive support, said pores being located in a greater concentration in said non-peripheral portion than in said peripheral portion; and (b) at least some of said pores being at least partially filled with a first solid polymer electrolyte, said first solid polymer electrolyte being non-conductive to electrons and comprising a dispersed reduced noble metal or noble metal oxide.
