Electrocatalysts for hydrogen

Several activities, if successful, would strongly boost the prospects for fuel ceU technology. These include the development of (/) an active electrocatalyst for the direct electrochemical oxidation of methanol (2) improved electrocatalysts for oxygen reduction and (2) a more CO-tolerant electrocatalyst for hydrogen. A comprehensive assessment of the research needs for advancing fuel ceU technologies, conducted in the 1980s, is available (22). [Pg.586]

Cobalt phosphine complexes of the type CpCo(diphosphine) have been known since 1986 to be molecular electrocatalysts for hydrogen production [80]. Catalysis by this family of compounds occurs through a [CpCo (diphosphine)H] intermediate that is only reduced at relatively large overpotentials. This limitation has led to... [Pg.248]

At temperatures below about 125°C, CO adsorption on platinum is very strong. Even few ppms in the H2 stream cause substantial performance losses on the anode. Therefore, the use of platinum alone is not viable for HOR in the presence of CO in low temperature fuel cells. Thus, platinum-ruthenium, platinum-molybdenum and platinum-tin are being used as anode electrocatalysts for hydrogen oxidation in the presence of CO because they tolerate low ppms of CO without excessive polarization losses. Timgsten carbide (WC) also shows high CO-tolerance [38,44]. [Pg.255]
