ABSTRACT:
An exemplary proton exchange membrane fuel cell includes a light-pervious first end plate, a second end plate, a light-pervious first bipolar plate, a second bipolar plate, and a membrane electrode assembly. The light-pervious first bipolar plate is arranged adjacent to the first end plate and capable of transmitting light having a given wavelength therethrough. The second bipolar plate is capable of having oxidant fed therein. The membrane electrode assembly includes a proton exchange membrane, and an anode and a cathode arranged at opposite sides of the proton exchange membrane. The anode is capable of having fuel fed therein, and includes a first catalyst layer containing photo-catalyst and noble metal such that the light is capable of activating the first catalyst layer to dissociate the fuel thereon.
