Abstract
A method for forming a membrane electrode diffusion assembly for use in an ion exchange membrane fuel cell is described and which includes, providing an ion conducting electrolyte membrane having opposite sides; and applying a first diffusion layer to one of the opposite sides of the ion conducting electrolyte membrane by the application of force sufficient to fabricate a resulting membrane electrode diffusion assembly which has an optimal operational temperature range when utilized in an ion exchange membrane fuel cell of less than about 95 degrees C.
