Understanding and identifying hydrogen fuel impurities

Webinar overview

Hydrogen fuel cells offer potential for clean, carbon-neutral transport, and stationary fuel cell applications, but providing an unadulterated source of hydrogen can be a challenge. Contaminants introduced in production and along the hydrogen supply chain can damage fuel cells, shorten component lifespan and even increase pollution. Identification and quantitation of these impurities is fast becoming a focus for analytical laboratories.

In this webinar, we explain how to analyse a wide range of volatile organic (VOC) impurities from hydrogen fuel in a single run using “hydrogen-certified” thermal desorption with gas chromatography–mass spectrometry (GC–MS) and specific detectors (such as SCD), complying with relevant global standards. Thanks to optimised preconcentration technology, the technique has proven to be more sensitive than alternative techniques and systems, while the ability to run both on-line and off-line samples gives ultimate flexibility to the analyst.

Key learning objectives:

  • Gain an understanding of the relevant standard methods and associated expectations for hydrogen fuel impurity analysis.
  • Details on the optimisation of methodology for online and offline thermal desorption GC–MS or GC–SCD.

Who should watch:

  • Lab managers and researchers involved in hydrogen fuel impurities analysis.
  • Hydrogen fuel industry researchers
