Electrocatalysis combinatorial methods

It is worth noting that combinatorial chemistry has only been explored in the field of fuel cell electrocatalysis for a short time (around ten years). Therefore, it is still a developing and maturing technology. With improvement in both catalyst library preparation and screening techniques, combinatorial methods will become more important in new fuel cell electrocatalyst development. It is also believed that this combinatorial method will speed up new catalyst exploration, and thus accelerate developments toward PEM fuel cell breakthrough and commercialization.

Besides SECM, other speetroseopie mefliods, such as scanning differential electrochemical mass spectrometry (SDEMS) and IR thermography, were also used as combinatorial screening methods for fuel cell electrocatalysis. The principle of SDEMS is to use mass spectrometry to locally measure dissolved gases and volatile liquid species near flie surfaces of catalyst arrays. IR thermography is based on reaction heat mapping. The heat results from the fuel cell electrochemical reactions on the catalyst arrays. Both methods can obtain reaction...
