Problems solved by technology
[0004] However, the existing technology uses external circulation for secondary utilization, which has the following problems: the high-temperature circulation pump is expensive, difficult to design, and introduces parasitic power consumption; if the ejector is set for external circulation, the adjustable performance of the system Poor, not suitable for variable working conditions
Moreover, no matter what method is used to carry out external circulation, it objectively increases the complexity of the system pipeline and increases the volume and cost of the fuel cell.
At the same time, most current stacks are sealed with glass ceramics, which has low reliability and poor thermal cycle performance

The invention provides an electrode sealing plate, a self-circulation electric pile and a self-circulation electric pile group. The electrode sealing plate provided by the invention is provided with a sealing frame and a middle region surrounded by the sealing frame, and the middle region forms a gas accommodating space; a plurality of cathode through holes and a plurality of anode through holes are formed in the sealing frame in the vertical direction, the cathode through holes comprise a first cathode through hole and a second cathode through hole, and the anode through holes comprise a first anode through hole, a second anode through hole and a third anode through hole; at least two of the cathode through holes are communicated with the middle region, or at least two of the anode through holes are communicated with the middle region. By using the electrode sealing plate provided by the invention in an electric pile, a circulation loop can be directly formed in the electric pile to reuse residual gas, so that many problems caused by low gas utilization rate and need of setting external circulation of a conventional electric pile are fundamentally solved.
Description
technical field [0001] The invention belongs to the field of fuel cells, and in particular relates to an electrode sealing plate, a self-circulating stack and a self-circulating stack group. Background technique [0002] At present, the global economy is facing a huge energy crisis, and the disadvantages of limited reserves and serious pollution of traditional fossil fuels are constantly emerging. Fuel cells have high thermal efficiency, produce very little harmful gas in the reaction, and have no mechanical transmission parts, so they do not produce noise during the working process, which is a research hotspot in the field of new energy. [0003] For a fuel cell, whether it is a primary battery mode or an electrolytic cell mode, due to the limited power of a single electrode unit, multiple electrode units are usually stacked to form a stack to work. During the working process of the electric stack, the cathode gas and the anode gas respectively flow through the cathode and...
