Commercially available state-of-art Pt-Ru/C anode catalysts have optimal Pt:Ru ratio between 1:1 to 2:1, which still possesses very high Pt ratio and thus practically hinders the commercialization of the fuel cell. Combinatorial method based on a multiple sample approach is now an important technique and has been developed as a promising alternatives method over conventional “one at a time” method for the discovery of new materials. In this work, some active PtRuCoW quaternary electrocatalysts are explored as anode catalyst for proton exchange membrane fuel cell (PEMFC) using a robotic dispenser and combinatorial optical screening method. In current combinatorial screening, pH change associated with fuel (methanol or hydrogen) oxidation allows one to differentiate active catalysts using fluorescent acid?base indicators. New quaternary electrocatalysts possessing relatively low Pt ratios compared to that of commercial binary PtRu was found to be very active for fuel oxidation and considerably improved the fuel cell performance. The combinatorial approach was found very useful for finding active multi-component catalyst compositions fast and cost-effectively through rational design of multiple sample approach.
