气体传感器用于促进氢的安全使用，例如燃料电池和氢燃料汽车。新的传感器的发展，旨在满足日益严格的性能要求，在新兴的应用，审查。结合不同的检测原理，即基于电化学电池、半导体或场效应的传感器与导热传感或催化燃烧元件相结合，在一个新的测量系统中的策略。这扩展了传感器的动态测量范围，同时提高了传感器的可靠性，通过多种冗余实现更高的安全完整性。从测量范围、传感器响应时间和低工作温度等关键工作参数出发，对新型纳米材料、纳米线、碳管和石墨烯的应用以及电子元件和光学元件的改进进行了评价。Copyright (C) 2014, Hydrogen Energy Publications， LLC.由Elsevier Ltd.出版。版权所有。
Gas sensors are applied for facilitating the safe use of hydrogen in, for example, fuel cell and hydrogen fuelled vehicles. New sensor developments, aimed at meeting the increasingly stringent performance requirements in emerging applications, are reviewed. The strategy of combining different detection principles, i.e. sensors based on electrochemical cells, semiconductors or field effects in combination with thermal conductivity sensing or catalytic combustion elements, in one new measuring system is reported. This extends the dynamic measuring range of the sensor while improving sensor reliability to achieve higher safety integrity through diverse redundancy. The application of new nanoscaled materials, nanowires, carbon tubes and graphene as well as the improvements in electronic components and optical elements are evaluated in view of key operating parameters such as measuring range, sensor response time and low working temperature.
