Abstract
A nonhumidified fuel cell is provided that includes a catalytic layer coupled to an anode or a cathode that is configured to accelerate an electrochemical reaction of a fuel gas or air, and a gas diffusion layer that has air pores diffusing the fuel gas or air to the catalytic layer and diffusing water generated by the electrochemical reaction with the fuel gas in the catalytic layer. In particular, a ratio of a volume of water to a volume of air pores of the gas diffusion layer ranges from about 0.1 to 0.4.
