    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 applying a second radiation-sensitive material to the first radiation-sensitive material. The first radiation-sensitive material has a first sensitivity. The second radiation-sensitive material has 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.

    摘要： A method for preventing a fuel cell voltage potential reversal including determining a relationship between the cell resistance and the current of a fuel cell stack at which a fuel cell voltage potential reversal will occur, operating the fuel cell stack according to a power demand requested, and determining the maximum cell resistance of the fuel cells in the stack. If the maximum cell resistance exceeds a threshold value for the current at which the fuel cell stack is being operated, the operation of the fuel cell stack is restricted to prevent the fuel cell voltage potential from reversing.

    摘要： A system for fabricating a radiation-cured component is provided. The system includes a radiation-sensitive material configured to at least one of initiate, polymerize, crosslink and dissociate with exposure to radiation, and at least one radiation source configured to project a radiation beam with a vector that does not intersect the radiation-sensitive material. The system further includes a radiation directing device that is selectively positionable to reflect the radiation beam in a desired direction and exposure the radiation-sensitive material to the radiation beam. A method for fabricating the radiation-cured components is also provided.
