Influence of Bi modification of Pt anode catalyst in direct formic acid fuel cells
Article Abstract:
The influence of Bi modification of Pt anode catalyst on the performance of direct formic acid fuel cells was investigated. Compared with the unmodified Pt anode, the Bi modified Pt (PtB[i.sub.m]) electrode prepared by under-potential deposition (UPD) caused faster electrocatalytic oxidation of formic acid at the same value of the overpotential, and thus PtB[i.sub.m] resulted in an increase in the power performance of direct formic acid fuel cells.

On the compensation effect in heterogeneous catalysis
Article Abstract:
A study shows that for a broad class of catalytic reactions, the compensation effect can be explained in terms of a switching of kinetic regimes. It also shows that the compensation effect in the rate is intimately linked to the underlying linear relationships between activation energy and stability of intermediates, which have been found to hold for a number of surface reactions.

High throughput experimental and theoretical predictive screening of materials - a comparative study of search strategies for new fuel cell anode catalysts
Article Abstract:
A comparative study of experimental and theoretical combinatorial and high-throughput screening methods for the development of novel materials is presented. Combinatorial experimental electrocatalysis was performed on a 64-element array. The results reveal very similar trends in electrocatalytic activity as a function of alloy composition.
