We learned that some investors asked BYD whether it is developing hydrogen fuel cells. In this regard, BYD said today that it has relevant research. The basic principle of a hydrogen fuel cell is the reverse reaction of electrolytic water, providing hydrogen and oxygen to the cathode and anode respectively. After hydrogen diffuses out through the cathode and reacts with the electrolyte, the released electrons reach the anode through an external load. Strictly speaking, a hydrogen fuel cell is a power generation device. Like a power plant, it is an electrochemical power generation device that directly converts chemical energy into electrical energy.
