Measurement of Trace Impurities in UHP Hydrogen for Fuel Cells Ensuring quality and safety

Measurement of Trace Impurities in UHP Hydrogen for Fuel Cells Measurement of Trace Impurities in UHP Hydrogen for Fuel Cells Hydrogen fuel cells offer greater reliability and a smaller carbon footprint compared to diesel and battery systems. Ultra-high purity (UHP) hydrogen is needed to ensure the optimum power generation and meeting rigorous quality standards is a challenge for producers, logistics and end users alike. Process Sensing Technologies has both the precision measurement instrumentation and the in-depth industry experience to provide a complete trace impurities detection for...

Measurement of Trace Impurities in UHP Hydrogen for Fuel Cells Why Is The Purity of H2 So Important and How Is It Achieved? Ultra-high purity hydrogen is required for use in fuel cells to maximise the lifespan of the electrolyte and catalysts used. The hydrogen used must conform to the ISO 14687 Part 2, which specifies hydrogen fuel quality requirements for all commercial hydrogen fuelling stations for proton exchange membrane (PEM) fuel cell vehicles (FCVs). The acceptable limits of contaminants are listed in the table below: Chemical Formula Hydrogen fuel index Minimum Analytical...
