FUEL CELL AND POLYMER ELECTROLYTE MEMBRANE

摘要

Fuel cell comprising: (a) an anode; (b) a cathode; (c) a polymer electrolyte membrane comprising at least one polyolefin, said polyolefin being obtained by- grafting side chains containing proton conductive functional groups onto a polyolefin having a crystallinity of from 41% to 48%, preferably of from 42% to 46%. According to one preferred embodiment, said fuel cell is a direct methanol fuel cell (DMFC).
