摘要： This invention relates generally to fuel cell system based on the distributed hydrogen production, and more particularly to a multi-fuel fuel cell system which is based on the distributed hydrogen production and fuel cell technologies is presented. The system includes fuel supply unit, fuel processor, fuel cell, heat exchange and oxidizer supply units. The fuel processor is a plasma-catalytic reformer. The heat exchange unit is a multiflow heat exchanger which is of a cascading structure from bottom top or a concentric cylinder structure from inside to outside. The multiflow heat exchanger has the function of balancing the heat of fuel processor and fuel cell. The fuel storage is connected to the fuel processor by the pipeline and provides fuel for the fuel processor. The outlet of fuel processor is connected via the multiflow heat exchanger to the fuel cell anode, and provides reactant for the fuel cell.

摘要： The present disclosure relates to a process for flattening the proton exchange membrane for the fuel cell and an apparatus therefor. This method is mainly used in the proton exchange membrane which is soaked with phosphoric acid, which will benefit that the control precision can be higher than the traditional adsorption method, and the mechanical transfer of proton exchange membrane can be realized so that the processing efficiency of proton exchange membrane in the process of fuel cell membrane electrode assembly is greatly improved. Furthermore, the efficiency of the membrane electrode assembly is improved.
