The development of low-Platinum content polymer electrolyte fuel cells (PEFCs) has been hindered by inexplicable reduction of oxygen reduction reaction (ORR) activity and unexpected O2mass transport resistance when catalysts have been interfaced with ionomer in a cathode catalyst layer. In this study,...
Achieving high catalytic performance with the lowest possible amount of platinum is critical for fuel cell cost reduction. Here we describe a method of preparing highly active yet stable electrocatalysts containing ultralow-loading platinum content by using cobalt or bimetallic cobalt and zinc zeolitic ...
proton exchange membrane fuel cellAn ultra﹍ow﹑latinum catalyst based on finely dispersed platinum (Pt) deposited on a highly porous complex microporous layer was investigated as a candidate of durable anode catalyst for hydrogen oxidation reaction (HOR) in proton exchange membrane fuel cells. ...

Due to its sluggish kinetics, ORR became the major contemporary technological hurdle for electrochemists, as it hampers the commercialization of fuel cell (FC) technologies. Downsizing the metal particles to nanoscale introduces unexpected fundamental modifications compared to the corresponding bulk state. ...
The main difference between the two technologies is the catalyst material: in biological fuel cells the catalytic power is derived from a microorganism or an enzyme instead of the usual platinum-based transition metal catalysts. Activity in connection with biocatalytic fuel cells has been lively ...
