摘要： An electric vehicle is described that has fuel cells and rechargeable batteries. The fuel cells are sized to produce an electric power output within their peak fuel efficiency range approximately equal to an anticipated average electric power requirement of the electric vehicle over a projected work cycle. The rechargeable batteries are sized to provide electric power up to the anticipated maximum power draw over the anticipated work cycle. An electrical vehicle controller operates the fuel cells within their highest fuel efficiency range during normal operations and maintains the battery state of charge in an optimal longevity range using a portion of the output of the fuel cells. The batteries are employed to handle short-term power requirements that exceed the output of the fuel cells.

摘要： An electrochemical hydrogen compression system includes a hydrogen compression stack, and a control device. The control device is equipped with an operation control unit that causes hydrogen gas to be supplied to a hydrogen compression stack, together with causing an electrical current to be supplied to the hydrogen compression stack from an electrical power source device, and causes a compression operation to be executed by the hydrogen compression stack, and an operation stop control unit which, upon receiving an operation stop command during execution of the compression operation, causes the liquid water to be supplied to the hydrogen compression stack, and thereafter causes the hydrogen gas to be supplied to the hydrogen compression stack.
