    摘要: An electrochemical cell includes a pair of bipolar plates and a membrane electrode assembly between the bipolar plates. The electrochemical cell further includes 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. Further, the electrochemical cell includes 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. The first seal is configured to leak the first fluid into the intermediate pressure zone when the first seal unseats.

    摘要: An electrochemical cell includes a pair of bipolar plates and a membrane electrode assembly between the bipolar plates. The membrane electrode assembly comprises an anode compartment, a cathode compartment, and a proton exchange membrane disposed therebetween. The cell further includes a sealing surface formed in one of the pair of bipolar plates and a gasket located between the sealing surface and the proton exchange membrane. The gasket is configured to plastically deform to create a seal about one of the cathode compartment or the anode compartment. The sealing surface can include one or more protrusions.

    摘要: The present disclosure is directed towards a method and a system for monitoring the performance of an electrochemical cell stack. Monitoring can be performed remotely by measuring the voltage across the stack, and comparing the measured values to predetermined reference values to determine the condition of the stack. Monitoring of the stack voltage enables detection of performance decay, which in turn enables preemptive repair of the stack prior to catastrophic failure.
