FUEL CELL INCORPORATING A POLYMER ELECTROLYTE MEMBRANE GRAFTED BY IRRADIATION |
摘要 |
Fuel cell comprising: (a) an anode; (b) a cathode; (c) a polymer electrolyte membrane placed between the anode and the cathode which comprises at least o ne polyolefin grafted with side chains containing proton conductive functional groups; wherein said fuel cell has: a value of cell resistance at 90 ~C not higher than 0.30 .OMEGA. cm2, preferably comprised between 0.2 .OMEGA. cm2 a nd 0.25 .OMEGA. cm2, more preferably comprised between 0.05 .OMEGA. cm2 and 0.2 0 .OMEGA. cm2; a value of cell resistance at 20 ~C differing from the value of cell resistance at 90 ~C of an amount not higher than 90%, preferably not higher than 70%, more preferably not higher than 50%, with respect to the value of cell resistance at 90 ~C. Preferably, said fuel cell is a direct methanol fuel cell (DMFC). |
