Claim 0:
1. An electrochemical device comprising:
an electrochemical cell including a first electrode having a first flow path, a second electrode having a second flow path, and a separating membrane sandwiched between the first electrode and the second electrode;
a gas-liquid separation tank which is connected to the first flow path of the first electrode and to which a product produced at the first electrode and water permeating from the second electrode to the first electrode are sent at an operation time;
an operating pipe connected to the first flow path of the first electrode and a gas portion of the gas-liquid separation tank; and
a water sealing pipe which is connected to a liquid portion of the gas-liquid separation tank and the operating pipe, and to send water in the gas-liquid separation tank to the first flow path of the first electrode at a stop time, wherein
the water sealing pipe is connected via the operating pipe to an opening being an outlet of hydrogen in the first flow path at an operation time, and has a check valve, and
an electromagnetic valve is connected to the opening being an outlet of water in the first flow path at a stop time.
