The invention provides a novel fuel cell flow field plate, which comprises an air inlet, interdigital flow field runners, ridges, a flow field plate, an air outlet and a single serpentine flow field runner, wherein the air inlet is arranged at the upper left part of the flow field plate; the air outlet is arranged at the lower right part of the flow field plate; the single serpentine flow field runner is arranged between the interdigital flow field runners; the ridges are arranged between the interdigital flow field runners and the single serpentine flow field runner; the air inlet is arranged in a manner of communicating with the interdigital flow field runners and the single serpentine flow field runner; and the air outlet is arranged in a manner of communicating with the interdigital flow field runners and the single serpentine flow field runner. The ridges and the runners are set into circular arcs at the corners, so that a ''flooding phenomenon'' caused by accumulation of products and water at the corners can be prevented, and the novel fuel cell flow field plate has the drainage performance of the single serpentine flow field runner and also has the performance of uniformly distributing a reactant gas through the interdigital runners.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a novel fuel cell flow field plate. Background technique [0002] Fuel cell power generation technology is a new generation of power generation technology after thermal power, hydropower and nuclear power. Because of its many outstanding advantages, it has become a new energy technology with great development prospects. It is considered to be the first clean and efficient power generation technology in the future. choose. The flow field is one of the important components of the fuel cell. Its main function is to evenly distribute the fuel and oxidant, and to export the heat, water and exhaust generated by the electrochemical reaction, so as to maintain the good performance and long service life of the fuel cell. Therefore, the flow field structure has an important influence on the performance of the fuel cell. [0003] There are many types of flow fields, commonly used are p...
