Direct Urea Fuel Cells Based on CuNi Plated Cloth as Anode Catalyst

Characteristics of direct urea fuel cells based on CuNi plated cloth as catalyst and current collector are reported. The power was significantly enhanced by coating the CuNi cloth with a conducting polymer, PEDOT*PSS. The cell exhibited the open circuit voltage of 0.68 V and the maximum power density of 1.88 mW cm−2 for 0.5 M urea at the room temperature.
