Hydrogen Energy Analysis Solutions for Quality Control of Hydrogen
Measurement of Impurities in Hydrogen Gas
Impurities in hydrogen production affect subsequent industrial processes. Consequently, strict purity standards have been defined for hydrogen used in fuel cells (ISO 14687-2019). This is because if hydrogen contains carbon monoxide, sulfur components, etc., the catalyst of the fuel cell will be damaged. The hydrogen fuel standard for FCVs (ISO 14687 Type II Grade D) defines many items to be controlled, and Shimadzu analytical instruments can play a role in analyzing these items.

Quality control of hydrogen using LabSolutions
In order to meet all of the hydrogen quality control items stipulated by ISO14687-2019, analysis using multiple analyzers is required. By using Shimadzu's integrated workstation LabSolutions CS, all analysis data is managed in a database on the server computer, so data can be read from any computer on the network.
Strength Testing in a Hydrogen Environment
Due to its exposure to high-pressure hydrogen gas environments, the metal in hydrogen gas tubing must be resistant to hydrogen embrittlement. Therefore, to evaluate hydrogen brittleness, a tensile testing system was designed to test tensile strength at extremely slow speeds in a hydrogen gas environment.
