Problems solved by technology
[0004] Although the metal plates in the aforementioned two patents are structurally designed with flow channels for the reactive gas and coolant to form a flow field for the reactive gas, they do not consider the heating and humidification of the reactive gas, so additional devices are needed to achieve this. , in this way, in addition to increasing the volume of the entire fuel cell system, it also increases the production cost, which is not conducive to the commercialization and promotion of fuel cells

The invention provides a pole plate, a pole plate group and a fuel cell. The pole plate can be applied in the fuel cell. An outer surface of the pole plate is provided with a plurality of gas channels, and at least a reaction gas humidification path. The reaction gas humidification path is provided with at least a humidification section used to absorb water molecules generated after fuel cell reaction, so that the reaction gas enters the fuel cell through a reaction gas inlet and flows through thehumidification section in the reaction gas humidification path. Heating andhumidification of the reaction gas are realized by using heat and the water molecules generated after the fuel cell reaction.
Description
technical field [0001] The present invention is related to fuel cells, in particular to a pole plate for a fuel cell, a pole plate group and a fuel cell. In addition to uniformly distributing the reactant gas of the fuel cell on the reaction surface, the polar plate can also properly heat and humidify the reactant gas, as well as enhance heat dissipation. Background technique [0002] In recent years, all kinds of pollution caused by petrochemical energy have caused the average temperature of the earth to rise and various climate anomalies. At the same time, it has also promoted the increasing demand for green alternative energy. Because the reactants used in fuel cells are low-cost hydrogen And oxygen, and the product after the electrochemical reaction is completely zero-pollution water, and the process used is similar to that of a general fuel generator. An important component of the Reaction Gas Flow Field. [0003] U.S. Patent No. US6,261,710B1 "Sheet Metal Bipolar Des...
