An experimental investigation in to the use of the heteropolyacids in PEM fuel cell applications as either a membrane component or as an electro-catalyst.

摘要

The widespread application of the PEM fuel cell is limited by the high cost of the technology.Raising the temperature of operation of a PEM cell from 80degC to >165degC would reduce cost by allowing lower loadings of precious metal catalyst,higher tolerances for CO in reformed hydrogen fuel feeds and the cogeneration of steam for heating applications.
