Description

Technical field [0001] The invention belongs to the technical field of new energy, in particular to the technical field of methanol-water hydrogen production, and in particular relates to a methanol-water instant hydrogen production system that can be applied to vehicle fuel cells, and a method for preparing hydrogen using the system. 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 the cathode respectively. After the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through an external load. Since hydrogen fuel cells generate electricity and water through the electrochemical reaction of hydrogen and oxygen, they are not only completely pollution-free, but also avoid the time-consuming ...
