Description

technical field [0001] The invention relates to a hydrogen generating device, in particular to a low-CO micro-hydrogen generating device utilizing methanol steam reforming, and belongs to the technical field of micro-hydrogen generation. Background technique [0002] CO, refers to the molecular formula of carbon monoxide, which is composed of an oxygen atom and a carbon atom connected by a covalent bond. Under normal conditions, carbon monoxide is a colorless, odorless, tasteless, poisonous gas with flammability, reduction and toxicity. . [0003] Fuel cell technology is an efficient and clean energy technology that converts chemical energy into electrical energy. Among them, low-temperature hydrogen-oxygen fuel cells with relatively mature technology have shown good application prospects due to their advantages such as simple structure, fast start-up, and low operating noise. But for portable applications, there are two problems with low-temperature oxyalkylene-based batt...
