Abstract

The present disclosure is intended to prevent blockage of a path that allows a fluid to flow to a predetermined position where a pressure of the fluid is applied to a cell unit. An electrochemical compressor according to an embodiment includes first and second members, an elastic body, a fluid chamber, and a fluid path. The elastic body exerts an elastic force in a direction in which the first member and the second member are pushed apart from each other, and thereby presses a stack of electrochemical cells. The fluid chamber has the elastic body disposed therein and receives boosted gas flowing thereinto, the fluid chamber allowing the boosted gas to apply a pressure to push the first member and the second member apart from each other. The fluid path connects the fluid chamber to a flow path into which the boosted gas is discharged from the electrochemical cells.

Dependent claims

An electrochemical compressor comprising:

a first member;
a second member racing the first member;
an elastic body that exerts an elastic force in a direction in which the first member and the second member, are pushed apart from each other, and thereby presses a stack of electrochemical cells in each of which s gas supplied thereto is boosted by being moved by electricity from one side to an opposite side of a solid polymer electrolyte membrane as a partition wall;
a fluid chamber that has the elastic body disposed therein end receives the boosted gas flowing thereinto, the fluid chamber allowing the boosted gas to apply a pressure in the direction in which the first member and the second member are pushed apart from each other;
and
a first fluid path formed on at least one of the first member or the second member, the first fluid path connecting the fluid chamber to a flow path into which the boosted gas is discharged from the electrochemical cells,
wherein at least one of the first member or the second member introduces the boosted gas into an interior thereof such that the stack of electrochemical cells is pressed by means of the pressure of the boosted gas.
