Fuel cell anode electrode, method of making the fuel cell anode electrode, and fuel cell containing the fuel cell anode electrode

摘要

A fuel cell anode electrode for use in fuel cells utilizing fuel electrolyte mixtures of methanol in potassium hydroxide electrolyte and ethylene glycol in potassium hydroxide electrolyte is made by pressing a paste mix of noble metal powder, graphite, and teflon onto a screen current collector, drying the electrode so formed, cathodically charging the electrode at a current density of about 21/2 to 10 mA/cm.sup. 2 for about 2 to about 6 minutes to deposit lead through electrolysis using a saturated solution of lead chloride, anodically charging the electrode for about 2 to about 12 minutes to oxidize the lead to lead dioxide, washing the electrode with distilled water, and drying the electrode.
