Patent abstract
Thin films of inexpensive composite polymer electrolyte membranes containing inorganic cation exchange materials including various clay based fillers are fabricated by solution casting. The membranes exhibit higher ion exchange capacity, proton conductivity and/or lower gas crossover. In general, the composite membranes exhibit excellent physicochemical properties and superior fuel cell performance in hydrogen oxygen fuel cells.
