POLYMERELEKTROLYT FÜR EINE BRENNSTOFFZELLE DES FESTPOLYMERTYPS UND BRENNSTOFFZELLE |
摘要 |
A polyelectrolyte for a solid polymeric fuel cell comprising an aromatic polyether sulfone block copolymer comprising a hydrophilic segment containing sulfonic acid groups and a hydrophobic segment having no sulfonic acid group at a hydrophilic segment weight fraction W2 to hydrophobic segment weight fraction W1 ratio falling within a range of 0.6<W2/W1<2.0. The polyelectrolyte for a solid polymeric fuel cell is inexpensive and durable, and its proton conductivity is less influenced by humidity and temperature. |
