Hydrogen energy society needs stable supply of high pressure hydrogen gas at 40MPa or more than that. However, conventional booster, which is mechanically driven, has rather low reliability. Against this situation we expect electrochemically-driven booster called as hydrogen pump, where hydrogen gas is pressurized by the immigration of the gas from anode to cathode through DC loaded MEA (membrane electrode assembly). The hydrogen pump is predicted that it has high reliability because of no mechanical links and that it has high efficiency because isothermal process is done in principle. Here we evaluate the minimum power of hydrogen pump and the concerns inherently existed there such as back diffusion and membrane breakdown. In addition, we show a prototype model of hydrogen pump.
