PURPOSE:To obtain a low-cost fuel cell in which a platinum-system catalyst is not used by using Cu2O as a catalyst for the oxidant electrode. CONSTITUTION:Cu2O is used as a catalyst for an oxidant electrode. Cu2O in powdered form is mixed with a conductive element such as flaked graphite or active carbon in a ratio by weight of 1:10-10:1 to make an oxidant electrode. The catalytic activity of Cu2O powder tends to increase with decreased crystallinity. That is to say, it depends on grain diameter, surface area, surface state and similar factors. Among Cu2O powders, one produced by subjecting Cu(CH3COO)2 to hydrazine reduction at room temperature is preferred because it has the greatest catalytic activity. |
