    摘要: A proton exchange membrane fuel cell including a membrane electrode assembly comprising a proton transmissive membrane, a catalytic anode layer on one face of the membrane, and a catalytic cathode layer on the other face of the membrane. The fuel cell further includes a gas distribution layer on each of the cathode and anode layers defining a gas flow field extending over each of the catalytic layers. The membrane electrode assembly has a convoluted configuration whereby to increase the ratio of membrane area to planar fuel cell area and thereby increase the electrical output of the fuel cell for a given planar area size fuel cell. The convoluted configuration of the membrane electrode assembly also facilitates the division of the gas distribution layers into separate parallel channels thereby allowing the use of an inexpensive foam material for the gas distribution layers irrespective of the inherent variations in porosity of foam materials.

    摘要: A method for fabricating a radiation-cured structure is provided. The method includes the steps of providing a first radiation-sensitive material and a second radiation-sensitive material adjacent the first radiation-sensitive material. The first radiation-sensitive material has a first sensitivity. The second radiation-sensitive material has the first sensitivity and a second sensitivity different from the first sensitivity. At least one mask is placed between at least one radiation source and the first and second radiation-sensitive materials. The mask has a plurality of substantially radiation-transparent apertures. The first and second radiation-sensitive materials are then exposed to a plurality of radiation beams through the radiation-transparent apertures in the mask to form a first construct in the first radiation-sensitive material and a second construct in the second radiation-sensitive material. The first construct and the second construct cooperate to form the radiation-cured structure.
