ISO 21087 Hydrogen Analytical Testing for Fuel Cell Applications

ISO 21087:2019, "Hydrogen—Analytical measurement of hydrogen isotopic composition," specifies the analytical methods required to determine the isotopic composition of hydrogen in fuel cell applications. This standard is crucial for ensuring that hydrogen used in fuel cells meets stringent quality and purity requirements, thereby enhancing performance and lifespan.

The primary focus of this testing involves measuring the percentage abundance of ¹H (protium) and ²D (deuterium), which are key isotopes in the context of hydrogen used for fuel cells. The process typically begins with a sample preparation phase, where the hydrogen is extracted from its source or supply stream using cryogenic distillation techniques. This step ensures that impurities such as noble gases and other contaminants are minimized.

The analysis itself can be performed using several methods including mass spectrometry (MS) and nuclear magnetic resonance spectroscopy (NMR). MS provides high precision, particularly in separating different isotopic components, whereas NMR offers non-destructive sample analysis with the advantage of detecting not only isotopes but also hydrogen bonding. The choice between these methods depends on the required accuracy levels and budget constraints.

Once the isotopic composition is determined, it influences several aspects critical to fuel cell performance:

Electrochemical Efficiency: Higher purity hydrogen yields more efficient electrochemical reactions within the fuel cell stack.
Voltage Output Stability: Consistent isotopic ratios ensure uniform voltage output across different cells, crucial for reliable power generation.
Durability: Impure hydrogen can lead to accelerated degradation of catalysts and membrane materials within the fuel cell.

Compliance with ISO 21087 is mandatory in many jurisdictions where high-purity hydrogen supply chains are regulated. This compliance ensures that manufacturers and suppliers adhere to industry best practices, ultimately leading to safer and more efficient energy systems.

Why It Matters

The significance of ISO 21087 cannot be overstated in the context of fuel cell technology. Hydrogen isotopic composition plays a pivotal role in the performance and longevity of fuel cells, which are critical components in renewable energy systems such as hydrogen-powered vehicles and stationary power plants.

One key reason for its importance is the direct impact on electrochemical efficiency. Fuel cells rely on pure hydrogen to generate electricity through an exothermic reaction with oxygen. The presence of isotopes like deuterium can slightly alter this process, affecting overall efficiency. By ensuring that the hydrogen meets the specified purity levels outlined in ISO 21087, fuel cell manufacturers and operators can optimize their systems for maximum performance.

Another critical aspect is voltage output stability. Fuel cells are designed to operate within specific voltage ranges to ensure optimal power generation. Variations in isotopic composition can lead to fluctuations in voltage output, which can be detrimental to the system's reliability and efficiency. ISO 21087 testing helps maintain consistent voltage levels by ensuring that only hydrogen with acceptable isotopic ratios is used.

Durability is also a major concern. Impure hydrogen can accelerate the degradation of catalysts and membrane materials within fuel cells, shortening their operational lifespan. By adhering to ISO 21087 standards, manufacturers can ensure that they are using only high-purity hydrogen, which in turn extends the service life of these critical components.

In summary, compliance with ISO 21087 is essential for achieving optimal performance, reliability, and longevity in fuel cell applications. It ensures that the hydrogen used meets stringent quality standards, leading to more efficient and sustainable energy systems.
