Description

technical field [0001] The invention relates to a production process of a novel bipolar plate, in particular to a mechanized production process for a composite bipolar plate of a proton exchange membrane fuel cell. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) is a power generation device that directly converts the chemical energy in hydrogen fuel and oxidant into electrical energy and its products. PEMFC single cell voltage is very low, about 0.6 ~ 0.7V, in order to obtain useful current and voltage, it is necessary to connect multiple single cells in series to form a battery stack. The separator used to separate two adjacent single cells is called a bipolar plate. In order to remove the heat of reaction from the fuel cell stack, a coolant channel is designed in the middle of each bipolar plate. Therefore, the usual bipolar plates are made of The anode plate with flow field, cathode plate and coolant flow field are composed. In order to pass cur...
