22. Transition metal ion-chelating ordered mesoporous carbons as noble metal-free fuel cell catalysts
Abstract : Polymer electrolyte membrane fuel cells offer promising possibilities for clean and efficient chemical to electrical energy conversion, though their high price makes them financially unappealing. This is to a large part due to the high cost of the noble metal catalyst used in fuel cells, which makes development of new, cheap and active catalyst materials necessary. READ MORE

23. Electrochemical characterisation of porous cathodes in the polymer electrolyte fuel cell
Abstract : Polymer electrolyte fuel cells (PEFC) convert chemicalenergy into electrical energy with higher efficiency thaninternal combustion engines. They are particularly suited fortransportation applications or portable devices owing to theirhigh power density and low operating temperature. READ MORE
