What purity does the standard require, why is it so hard to maintain, and what does a specialised laboratory contribute? Here we answer the questions operators, planners and buyers ask us most often.
Fuel cells react sensitively to impurities. Even traces of water, sulphur compounds, carbon monoxide, ammonia, oils or particles can reduce performance and permanently damage the cell stack. Limit values are therefore in the range of single parts per billion – an order of magnitude that can only be demonstrated by measurement.
The analysis demonstrates whether the hydrogen meets the requirements of ISO 14687 and DIN EN 17124 for vehicle applications. For operators this evidence matters twice over: it safeguards reliable vehicle operation – and it documents the quality delivered should a damage claim arise.
Since 2021 we have specialised in hydrogen analytics to ISO 14687 and DIN EN 17124. In Berlin we operate one of the most advanced laboratories in Europe for this purpose; with our two mobile laboratories we test hydrogen purity on site across Europe.
We take care of sampling as well: we provide professional sampling kits and suitable sample containers and, on request, handle the entire transport logistics. For production sites we also plan and implement process monitoring systems that monitor gas quality 24/7.
