ELECTROCHEMICAL COMPRESSOR

Abstract:

The present disclosure is intended to provide an electrochemical compressor capable of preventing a liquid, such as water, from accumulating inside a piston. An electrochemical compressor according to an embodiment includes a housing chamber and a drain path. The housing chamber houses an elastic body that presses an electrochemical cell with its elastic force, and is configured to receive part of a gas compressed by the electrochemical cell, the part of the gas flowing into the housing chamber. In the electrochemical cell, the gas is supplied to an anode side of a solid polymer electrolyte membrane as a partition wall, and is compressed by being moved by electricity to a cathode side opposite to the anode side. The drain path allows a liquid in the housing chamber to be drained out of the housing chamber.
