We studied the isothermal hydrogen adsorption and reaction at the carbon and platinum (Pt) surface of the humidified E-TEK electrode of a polymer electrolyte fuel cell (PEMFC) with a Nafion ® 117 membrane by impedance spectroscopy at 30 and 50 • C. We found three rate-limiting steps, one of them is

Sn-promoted Pt-based catalysts were prepared by the chemical vapor deposition (CVD) of Sn on commercial Pt/C and PtRu/C catalysts using Sn(CH 3 ) 4 as an Sn precursor. The prepared catalysts showed higher CO tolerance than those prepared by adding Sn using an impregnation (IMP) method. This result w

The formation of OH radicals ( • OH) for polymer electrolyte fuel cell (PEFC) was investigated with a homemade test cell by means of a fluorescence probe method for several kinds of membrane electrode assembly (MEA) consisting of Nafion. After 12-h operation under open circuit condition, • OH was de
