摘要

Inorganic-organic hybrid membranes comprising an aliphatic backbone polymer and a trisiloxane bond were synthesized from a trisiloxane derivative, phosphonic acid acrylate, and vinylbenzotriazole, and used to prepare membrane electrode assembly (MEA) sandwiched between metallic glass separators (MGSs). The prepared MEA exhibited a higher cell voltage than that comprising carbon separators at 140 degrees C and 30% relative humidity for 50 h.
