  • Publication number: 20100248085
    Abstract: The present invention relates to a flow field plate of a fuel cell with airflow guiding gaskets, comprising a flat plate and airflow guiding gaskets. Each side of the flat plate has a reaction area, which includes a plurality of ribs and a plurality of grooves. Two airflow guiding gasket are respectively covered on the two sides of the flat plate, and a central hollowed region of each airflow guiding gasket is corresponding to the reaction area. An inlet hole of the flat plate communicates with the hollowed region and each inlet of the grooves through an inlet trough of the airflow guiding gasket. An outlet hole of the flat plate communicates with the hollowed region and each outlet of the grooves through an outlet trough of the airflow guiding gasket. Thus, the present invention is capable of significantly reducing the volume of the fuel cell and lowering the weight.

  • Publication number: 20070048564
    Abstract: The present invention is related to a fuel cell combining a stack and a reformer, which comprises a stack having a coupling part and a reformer having a conjugate part. The conjugate part of the reformer may couple to the coupling part of the stack. The full cell according to the present invention reduces the volume, fully utilizes thermal energy, and reduces the use of raw materials to minimize expenses.

  • Publication number: 20070042239
    Abstract: A fuel cell system has a distributor, at least one catalytic converter for the reformation reaction and a stack. When the fuel cell system has more than two catalytic converters for the reformation reaction a converging chamber can be added into the system to input the hydrogen gas generated by the catalytic converter for the reformation reaction to the stack. Therefore, the present invention can integrate the catalytic converter for the reformation reaction and the stack to reduce both the cost and fuel cell volume, and save fuel.
