Abstract
A sensor for monitoring hydrogen concentrations in gases, containing a solid electrolyte body, a detector electrode having a surface which is exposable to a gas to be monitored, and a reference electrode, in which the reference and detector electrodes make contact with the solid electrolyte, and the detector electrode contains a platinum metal or a platinum metal oxide.
Claims8
A sensor for monitoring hydrogen concentrations in gases, comprising:
- a solid electrolyte body comprising at least one of nasicon, titsicon, khibinskite, wadeite and .beta.-Al.sub.2 O.sub.3 ;
- a detector electrode having a surface to be exposed to a gas to be monitored;
- and
