Description

technical field [0001] The invention relates to the field of gas pressure self-balancing devices, in particular to a pressure self-balancing device for producing gas from electrolyzed water and its application. Background technique [0002] Electrolyzed water gas production is a hydrogen and oxygen production process that only consumes electric energy and water, and its gas production process is green and pollution-free. Under the current situation of increasingly severe energy and environmental problems, it is necessary to vigorously develop green energy, and electrolysis of water to gas is the only choice to realize green energy. There are hydrogen and oxygen in the gas produced by electrolysis of water, and hydrogen is a very clean energy carrier. Countries have invested a lot of manpower and financial resources in the development of hydrogen-related industries and technologies, such as hydrogen fuel cell vehicles and hydrogen fuel cell power generation. Although there a...
