Abstract

The migration of water and methanol across the hydrophilic membrane of hygen and methanol fuel cells from the anode to the cathode compartment decreases the electric energy output of such fuel cells. This migration is minimized by the precipitation in the pores of the membrane of zirconyl phosphate. A method and an apparatus for precipitaing zirconyl phosphate in the pores of membranes for hydrogen and methanol fuel cells are provided.
