Abstract
The present invention discloses various methods in which a quality of a diffusion media for use in a fuel cell assembly can be qualitatively evaluated. The material constant, an internal contact angle, a ratio of high and low energy pores, and an external contact angle can be calculated for the diffusion media and compared to a predetermined standard to evaluate the quality of the diffusion media.
