Abstract: There is a strong need to move away from the conventional fossil fuels used today. Hydrogen is a promising alternative and its use will significantly reduce harmful emissions if produced by renewable energy sources. However, the performance of PEM fuel cells is strongly dependent on the presence of impurities in the hydrogen gas. To ensure that the hydrogen quality meets the criteria specified in ISO 14687-2: 2012, it has to be analyzed for the presence of impurities.
Many of the impurities present in the hydrogen gas strongly adsorb and have maximum allowable levels at nmol/mol level posing stringent requirements to the analytical instrumentation and sampling system. An overview is given of the development of the analytical capabilities at VSL with respect to the analysis of selected analytes in hydrogen.
Summary: VSL has developed analytical capabilities at or below the specifications of ISO 14687-2 for the analysis of most of the specified analytes in hydrogen.
