1. An electrochemical cell comprising:
a pair of bipolar plates, wherein a sealing surface is formed in only one of the pair of bipolar plates,
a membrane electrode assembly located between the pair of bipolar plates, wherein the membrane electrode assembly comprises an anode compartment, a cathode compartment, and a proton exchange membrane disposed therebetween;
a first seal defining a high pressure zone, wherein the first seal is located between the bipolar plates and configured to contain a first fluid within the high pressure zone; and
a second seal defining an intermediate pressure zone, wherein the second seal is located between the bipolar plates and configured to contain a second fluid within the intermediate pressure zone;
wherein the first seal is formed by a gasket that is configured to plastically deform to create a seal about only one of the cathode compartment or the anode compartment.
