HYDROGEN GAS MANUFACTURING AND FILLING EQUIPMENT AND ELECTROCHEMICAL EQUIPMENT

The present invention is relative with an electrochemical apparatus including a hydrogen manufacturing and preserving device capable of manufacturing hydrogen and compressing and charging the so manufactured hydrogen. The apparatus includes an electrolytic unit (1) for generating a hydrogen gas on electrolysis, a pressurizing unit (2) for compressing the hydrogen gas generated by the electrolytic unit (1) and a charging unit (4) for charging the compressed hydrogen gas to the hydrogen gas tanks (50 to 58). The pressurizing unit (2) operates as a fuel cell unit run reversible on being supplied with the hydrogen gas from the charging unit (4) and with oxygen or an oxygen-containing gas.
