Abstract
An electrochemical reaction cell comprising an anode electrode, a cathode electrode, and a membrane electrode assembly (MEA). The MEA is positioned between the anode electrode and the cathode electrode. The anode electrode, the cathode electrode, and the MEA each have a corrugated shape and are contained within a recess of a housing.
Claims16
A membrane electrode assembly (MEA) comprising:
- an anode channel;
- a cathode channel;
- and
- a membrane positioned between the anode channel and the cathode channel and configured to form an interface therebetween,
- wherein each of the anode channel and the cathode channel comprises a rigid plate formed into a corrugated shape, the corrugated shape comprising alternating smooth peaks and valleys,
- wherein the anode channel, the membrane, and the cathode channel are configured to engage with each other in a mating relationship in which peaks and valleys of the anode channel match with corresponding peaks and valleys of the cathode channel such that the membrane conforms to the corrugated shape when engaged between the anode channel and the cathode channel, and
- wherein the anode channel, the membrane, and the cathode channel are configured to be received within a recess formed in an inner surface of a housing.

An electrochemical reaction cell comprising:
- an anode channel and a cathode channel each having a corrugated shape and configured to supply electric current to an external circuit during operation of the electrochemical reaction cell, wherein each of the anode channel and the cathode channel comprises a rigid plate formed into the corrugated shape, the corrugated shape comprising alternating smooth peaks and valleys, and wherein the peaks and valleys of the anode channel match with corresponding peaks and valleys of the cathode channel in a mating relationship;
- a membrane positioned between the anode channel and the cathode channel and configured to form an interface therebetween, wherein the membrane conforms to the corrugated shape when engaged between the anode channel and the cathode channel in the mating relationship;
- a housing having a recess formed in an inner surface thereof, the recess receiving the anode channel, the membrane, and the cathode channel therein;
- and
- an electrolyte fluid contained within the housing and in contact with the anode channel and the cathode channel.
