提出了一种基于聚苯并咪唑的质子聚合物电解质，用于室温下在空气中工作的氢传感器。在含氢惰性气体中的电位响应服从能斯特方程。在空气中，电动势是由氢氧化和氧还原产生的混合电位。在氢气分压从10{sup {minus}3}到1 atm的范围内，无论氢气浓度步长如何，响应时间都在30秒左右。
A protonic polymer electrolyte based on polybenzimidazole is proposed for use in a hydrogen sensor, operating at room temperature, in air. The potentiometric response in inert gas containing hydrogen obeys the Nernst equation. In air, the EMF is a mixed potential which results from the hydrogen oxidation and the oxygen reduction. The response time is of the order of 30 s whatever the hydrogen concentration step within the hydrogen partial pressure range from 10{sup {minus}3} to 1 atm.
