This discussion involves reactant transport into and out of the catalyst layer, poisoning of the catalyst by fuel impurities, and strategies to improve all of these issues. The chapter also deals with the problem of oxygen reduction at the cathode. The problems of reactant/product transport in ...
This invention discloses a catalyst material used in hydrogen-oxygen fuel cell, which is modified chitose film load metal chlorid material. The process is the following: to coat the modified chitose load chlorid material to the cell negative electrode to get a good catalyst ability in the alka...
Currently, a European team directed by scientists at Imperial College London has developed a catalyst using just iron, nitrogen and carbon — materials that are inexpensive and easily available — and shown that it can be used to operate a fuel cell at high power. Their outcomes are reported ...

High costs in materials and production are holding back the scalability of hydrogen fuel cells, but researchers have found a way to reduce costs by improving materials and processes in making fuel cells.
Fuel cells are usually named for their electrolytes. To date five different electrolyte materials have shown potential for commercial development. The five fuel cell types have different characteristics, which make each one suitable for some applications but not others. A short description of the ...
Hydrogen fuel cell catalyst The serialized electrocatalyst products have passed third-party testing, with the performance indicators of electrocatalyst uniformity, batch stability and consistency meeting the design requirements. Tested under the three-electrode system, the ECSA of the self-made platinum-...
The new catalyst was developed by Professor Héctor Abruña and colleagues from Cornell University, the National Institute for Materials Science in Ibaraki, Japan, and the University of Pennsylvania. They began with the knowledge that tungsten alloys resist CO poisoning. Tungsten is not used infuel...
