A method of operating a dead - end fuel cell using selective permeable membrane and periodic pulsation

摘要

The present invention provides an electrochemical device for generating electric power by a chemical reaction, a fuel supply unit for supplying fuel to a fuel electrode of the electrochemical device, an air supply unit for supplying air to an air electrode of the electrochemical device, and the electrochemical device. It includes a vibration unit for applying vibration, and a fuel recovery unit for discharging water generated in the electrochemical device and re-supplying fuel, and a high-efficiency electrochemical device by not discharging fuel used for electricity production reaction. It is for a closed electrochemical device system that can provide.
