Abstract
In an electrochemical hydrogen pump, an anode separator, an anode diffusion layer, an electrolyte membrane, a cathode diffusion layer and a cathode separator are laminated sequentially, in which the anode separator has a first recess portion that accommodates the anode diffusion layer, and a bottom surface of the first recess portion is a bowl-shaped curved surface having a protruding central portion; the cathode separator has a second recess portion that accommodates the cathode diffusion layer, and a bottom surface of the second recess portion is a bowl-shaped curved surface having a recessed central portion.
Claims9
An electrochemical pump comprising:
- an anode separator, an anode diffusion layer, an electrolyte membrane, a cathode diffusion layer, and a cathode separator laminated sequentially,
- wherein the anode separator has a first recess portion that accommodates the anode diffusion layer, and a bottom surface of the first recess portion is a bowl-shaped curved surface having a protruding central portion, and
- wherein the cathode separator has a second recess portion that accommodates the cathode diffusion layer, and a bottom surface of the second recess portion is a bowl-shaped curved surface having a recessed central portion.
An electrochemical pump comprising:
- an electrolyte membrane;
- a pair of plate-shaped diffusion layers disposed to be adjacent to both surfaces of the electrolyte membrane;
- and
- a pair of separators, each including a recess portion that accommodates one of the diffusion layers and pressing the one diffusion layer accommodated in the recess portion toward the electrolyte membrane,
- wherein a diameter of the one diffusion layer is smaller than a diameter of the respective recess portion in a state of not being pressed by the respective separator, and is equal to the diameter of the respective recess portion in a state of being pressed by the separator, and
- wherein a height of the one diffusion layer in a state of being pressed by the respective separator is lower than a height of the one diffusion layer in a state of not being pressed by the separator.
