โœฆ Synopsis

A significant improvement in hydrogen-air proton-exchange membrane (PEM) fuel cell performance has been achieved by the use of a pore-forming additive in the air electrode's active layer. The fuel cell was operated without significant loss of performance at atmospheric pressure and without humidification, through changes in the structure of the air electrode's substrate layer. Today's proton-exchange-membrane fuel cell (PEMFC) research and development is directed at improved performance, simplified operation and reduced weight. During the past few years, these characteristics have often appeared to have reached a plateau or point of saturation with regard to further improvement. Data obtained so far and scientific effort and achievement concerning performance have been summarised by researchers at Ballard.[') They concluded that further improvement in PEMFC performance might be achieved by systematic research in: (i)

Further refinements can be achieved by varying the print pattern across the cell, and by using multiple layers to control both the depth and structure of the layers within the pattern.

Precious-metal catalysts (predominantly Pt or Pt-based alloys supported on carbon) have traditionally been used to catalyze the electrode reactions in polymer electrolyte membrane (PEM) fuel cells. However as PEM fuel systems begin to approach commercial reality, there is an impending need to replac
