ABSTRACT:
A process is provided for removing contaminating residues left behind during fabrication of gas electrodes employed in metal/gas batteries, e.g., nickel/hydrogen batteries, and fuel cells employing gas electrodes. Such residues arise from depositing and sintering on a conductive, screen-type electrode substrate a platinum powder/polytetrafluoroethylene powder mixture containing a suspending agent. The residues of the suspending agent are removed by contacting the fabricated electrode with a solvent mixture comprising a first solvent, e.g., trichloroethylene, for dissolving the residues and a second solvent, e.g., ethanol, for wetting the polytetrafluoroethylene.
