Abstract

The invention relates to the technical field of cathode closed type fuel cells, and provides a fuel cell and a fuel cell power generation system. The fuel cell comprises a gas distribution plate and a cathode closed type electric pile, the first end face of the gas distribution plate makes contact with the first end face of the cathode closed type electric pile, the first end plate is provided with a cathode air inlet and a cathode air outlet, the first end face is provided with a cathode air inlet groove and a cathode air outlet groove, and the cathode air inlet and the cathode air outlet are communicated with the cathode air inlet groove and the cathode air outlet groove respectively. According to the fuel cell disclosed by the invention, the cathode gas inlet groove and the cathode gas outlet groove are formed in the gas distribution plate, so that the use of a cathode gas distribution pipeline is reduced, the length of the pipeline in a power generation system is reduced, the pipeline structure is simplified, and the gas pressure loss is reduced; and risks caused by complex processes such as gas pipe out-of-phase sealing and the like which must be adopted for achieving insulation between the electric piles when multiple piles of gas circuits are connected in the system are avoided, and integration of a power generation system is facilitated.

Description

technical field [0001] The invention relates to the technical field of cathode closed fuel cells, in particular to a fuel cell and a fuel cell power generation system. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy. It is mainly composed of four parts: anode, cathode, electrolyte and external circuit. [0003] The power of a fuel cell single cell is limited. In order to increase the power of the fuel cell, several single cells are usually assembled into a stack, and then multiple stacks are assembled into an integrated power generation system. The stack needs to use gas distribution during the integration process. The plates supply gas to the stack, and the end plate at one end of the closed cathode stack is provided with an anode inlet, an anode outlet, a cathode inlet and a cathode outlet for hydrogen and oxygen in and out, and the gas distribution board is provided with An anode inl...
