The invention provides a fuel cell bipolar plate, a single cell and a fuel cell. The bipolar plate includes: an anode plate and a cathode plate; the anode plate is provided with a fuel distribution area, and the fuel distribution area is provided with a fuel cover plate and a fuel distribution structure; And / or, the cathode plate is provided with an oxidant distribution area, and the oxidant distribution area is provided with an oxidant cover plate. The fuel cell bipolar plate of the present invention has fluid distribution areas on both the gas side and the water side. The overall flow uniformity is good and the distribution is easy to adjust. The gas side is a wave channel, and the water side can flow both horizontally and vertically. At the same time, the flow channel has no large corners to reduce local resistance loss, and the reduced pump work improves power generation efficiency. Compared with the compression seal, the pre-formed bonding process of the rubber gasket is used, and the reliability is improved, and there is no need for additional materials, processes and equipment such as injection molding machines, saving costs.
Description
technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a fuel cell bipolar plate, a single cell and a fuel cell. Background technique [0002] The internal system of the fuel cell is complex during operation, and the water heat management greatly affects the gas, liquid distribution and battery performance. [0003] Water management refers to maintaining the water balance in the battery in an optimal state. The goal is to remove excess liquid water in time to prevent the electrodes from being submerged in water and avoid severe water vapor dilution and film dehydration. [0004] The research content of thermal management is the generation and transfer of heat in the battery, the distribution of temperature field and the cooling method. The purpose is to promote the balance of heat absorption and discharge of the whole battery at a certain temperature value, and the temperature field of the whole battery is evenly distr...
