Open circuit voltage electrocatalyst

Tungsten carbide based non-Pt electrocatalyst have been evaluated for single cell performance of PEMFC. The power densities of WC/C (1 mg/cm ) and Ni-WC/C (1 mg/cm ) anodes fabricated by TPRe were 6.5 and 8.9 mW/cm, respectively, cathode of 20 wt% Pt and membrane of Naflon 117 (151). W2C (0.48 mg/cm ) anode catalyst was prepared by ball-milling of WO3, Mg, and C mixture and tested in a single cell mode at 80°C with Pt/C cathode (0.3 mg/cm ), Naflon 112 membrane, and H2/Air = 5. This electrocatalyst produced high current densities of 240 mA/cm (at 2 atm) and 280 mA/cm (at 3 atm) at 0.5 V, and an open circuit voltage of 0.95 V(152). These values represent the highest current density reported for WC-based anode in the literature. In the analysis, the material... [Pg.1393]
