Abstract

A method of decreasing contact resistance of a fuel cell by activating various surfaces of a fuel cell using a laser is disclosed. A surface layer of a resin binder of a homogeneous separator plate may be removed. In addition, a coating of a gas diffusion media in areas where the gas diffusion media contacts the separator plates may also be removed.
