Abstract

The present invention addresses the problem of providing an electrochemical booster device capable of preventing liquid such as water from accumulating inside a piston. In order to solve the problem, the present invention provides an electrochemical step-up device provided with a housing chamber and a discharge channel. The housing chamber houses an elastic body that presses an electrochemical cell by means of an elastic force, and a portion of a high-pressure gas that has been pressurized by the electrochemical cell flows into the housing chamber. The electrochemical cell uses electricity to move a supply gas supplied to the anode side to the cathode side, which is the opposite side of the partition wall, which is the solid polymer electrolyte membrane, and increases the voltage of the supply gas. The discharge channel discharges the liquid in the accommodation chamber to the outside of the accommodation chamber.

Description

technical field [0001] The invention relates to an electrochemical booster device. Background technique [0002] As a method of increasing the pressure of gas such as hydrogen gas, that is, increasing the pressure, there is a method of compressing by moving hydrogen gas through a solid polymer electrolyte membrane by electrochemistry, in addition to a mechanical compressor. This battery cell utilizes electricity to convert hydrogen gas supplied to the anode-side electrode into hydrogen ions. The hydrogen ions move in the solid polymer electrolyte membrane and bond with electrons on the cathode side electrode to form hydrogen gas. That is, the hydrogen gas is transferred to the other side of the solid polymer electrolyte membrane by electricity. If on the moved side there is a direct connection with, for example, a tank, the gas has nowhere to go and is compressed to high pressure. In order to increase the throughput of gas movement, that is, the boosting speed, a pluralit...
