Abstract
An electrochemical system includes a first stack, a first tank for storing high-pressure gas output from the first stack, a check valve disposed in a flow path connecting the first stack and the first tank, a first pressure sensor and a second pressure sensor connected respectively to the upstream and the downstream of the check valve, and a control unit. The control unit determines that an electrolyte membrane has been damaged when the pressure difference between the upstream and the downstream of the check valve exceeds a predetermined pressure.
Claims10
An electrochemical system comprising:
- a first stack including a membrane electrode assembly containing:
- an electrolyte membrane;
- and a first electrode and a second electrode sandwiching the membrane electrode assembly therebetween;
- a first tank configured to store a first gas having a high-pressure, output from the first stack;
- a check valve disposed in a flow path that connects the first stack and the first tank;
- a first pressure sensor connected to the flow path at an upstream of the check valve;
- a second pressure sensor connected to the flow path at a downstream of the check valve;
- and
- a processing circuitry, wherein the processing circuitry determines whether the electrolyte membrane has been damaged or not, based on a pressure detected by the first pressure sensor and a pressure detected by the second pressure sensor,
- wherein the processing circuitry obtains a differential pressure by subtracting the pressure detected by the first pressure sensor from the pressure detected by the second pressure sensor, and the processing circuitry determines that the electrolyte membrane has been damaged when the differential pressure exceeds a predetermined pressure.
