HYDROGEN STORAGE METHOD, HYDROGEN GAS PRODUCTION METHOD, AND HYDROGEN GAS PRODUCTION SYSTEM

摘要

The present invention relates to a hydrogen gas production method comprising: a first step of concentrating an aqueous solution containing a formic acid alkali metal sa a second step of protonating at least a portion of the formic acid alkali metal salt by electrodialysis to generate formic acid; and a third step of decomposing the formic acid to produce a hydrogen gas.
