Description

technical field [0001] The invention relates to the technical field of hydrogen fuel motors, in particular to a direct current metering device for blind signal separation of polymer hydrogen fuel cells. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load. [0003] Hydrogen fuel cells generally measure the electricity generated by the electric energy metering device. It is found in the use of the existing electric energy metering device that the long-term operation of the metering device will generate a large amount of heat. Excessive heat will make the metering of the m...
