MORE ACCURATE DETERMINATIONS OF HYDROGEN STORAGE AND CONTROLLING METHODS OF SIEVERTS APPARATUS

摘要

A hydrogen storage performance evaluation apparatus using a volume method and a control method thereof are provided to prevent damage to instrument due to corrosion and leakage of a pipe and a connection part by controlling the temperature of a constant temperature chamber using a thermoelectric element. A hydrogen storage performance evaluation apparatus using a volume method comprises a main body(10), a hydrogen supply pipe, a helium supply pipe, a main pipe, a test cell(66), and a vacuum pipe. The main body has a constant temperature chamber(20) maintaining the fixed temperature with a thermoelectric element. The hydrogen supply pipe supplies hydrogen to the constant temperature chamber. The helium supply pipe supplies the helium which is inactive gas to the constant temperature chamber. The main pipe is arranged inside the constant temperature chamber and one end of the main pipe is supplied with each gas from the hydrogen supply pipe and the helium supply pipe and the other end has a outlet which is exposed from the outside of the constant temperature chamber. The test cell is detachably mounted at the end part of an outlet pipe(60) which is drawn out of the main body. The vacuum pipe is connected to the main pipe.
