Abstract
A fuel cell includes a cathode, an anode, an electrolyte membrane interposed between the cathode and the anode, and a porous layer containing a moisture retentive material. The anode includes an anode catalyst layer adjacent to the electrolyte membrane and an anode diffusion layer adjacent to the anode catalyst layer, and the porous layer is disposed between the anode catalyst layer and the electrolyte membrane. The performance of the fuel cell can be stably maintained even when a fuel supply is temporarily interrupted due to a malfunction of a pump or clogging of a fuel channel.
