摘要
Hydrogen (H-2), as a source of energy, continues to be a compelling choice in applications ranging from fuel cells and propulsion systems to feedstock for chemical, metallurgical and other industrial processes. H-2, being a clean, reliable, and affordable source, is finding ever increasing use in distributed electric power generation and H-2 fuelled cars. Although still under 0.1%, the distributed use of H-2 is the fastest growing area. In distributed H-2 storage, distribution, and consumption, safety continues to be a critical aspect. Affordable safety systems for distributed H-2 applications are critical for the H-2 economy to take hold. Advances in H-2 sensors are driven by specificity, reliability, repeatability, stability, cost, size, response time, recovery time, operating temperature, humidity range, and power consumption. Ambient temperature sensors for H-2 detection are increasingly being explored as they offer specificity, stability and robustness of high temperature sensors with lower operational costs and significantly longer operational lifetimes. This review summarizes and highlights recent developments in room temperature H-2 sensors.
