Title:
ELECTROCHEMICAL DEVICE
Document Type and Number:
Japanese Patent JP2014060113
Kind Code:
A
Abstract:

To obtain an electrochemical device which can be assembled and removed with a simple structure without impairing an electrochemical cell, while preventing gas leakage.

An electrochemical device includes an electrochemical cell 10, a cell holder 18, gaskets 19a, 19b, and a sealant 21. The electrochemical cell 10 has an electrolyte membrane, an oxide electrode 12b provided on one surface of the electrolyte membrane, and a hydrogen electrode provided on the reverse side with respect to the oxide electrode 12b while sandwiching the electrolyte membrane. The cell holder 18 has a first opening having an inside diameter substantially equal to the diameter of the electrochemical cell 10 at the outer edge thereof, and the electrochemical cell 10 is inserted into the first opening. In order to cover the surface of the cell holder 18 and the partial surface of the electrochemical cell 10, the gaskets 19a, 19b have a second opening formed with an inside diameter narrower than that of the first opening. The sealant 21 fills the gaps between the electrochemical cell 10, the cell holder 18 and the gaskets 19a, 19b.
