Fig. 6-6 Preparation of polymer electrolyte fuel
cell membranes by a two-step irradiation process

High-performance fuel-cell membranes for operation at high methanol concentrations were successfully developed by establishing fluororesin base films capable of radiation-crosslinking even at room temperature and four new graft components from monomers and chemical crosslinkers which offer high durability and high ion conductivity.
