The steel contains a small amount of hydrogen which will escape during the heat treatment The hydrogen pressure in 16MnRE steel was investigated with a hydrogen sensor which used SrCe0 95Yb0 05O3-alpha proton conductor as a solid electrolyte YHx+YH2-z, as a solid state reference electrode and Ni wire as electrode constructing a hydrogen concentration cell shown as Ni vertical bar YHx+YH2-z vertical bar SrCe0 95Yb0 05O3-alpha vertical bar[H](steel) vertical bar Ni The response time of sensor is less than 10 s The relational expression of hydrogen partial pressure with temperatures was determined using two shape proton conductors The results showed the regularity in experimental temperature range and the hydrogen partial pressure increased as its temperature was raised
