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 14687-2023). 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 ISO14687-2023, 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.
