Abstract
An illustrative example hydrogen concentration sensor includes a first end plate. A hydrogen evolving electrode assembly that generates hydrogen is situated adjacent the first end plate and at least partially exposed through an opening through the end plate. A separator plate is between the hydrogen evolving electrode assembly and a detection electrode assembly. The separator plate includes a passage to allow a flow of hydrogen generated by the hydrogen evolving electrode assembly to the detection electrode assembly. A second end plate is situated adjacent the detection electrode assembly and includes a second opening where a portion of the detection electrode assembly is exposed to a fluid of interest to provide an indication of a concentration of hydrogen in the fluid of interest.
