ABSTRACT:
A catalyst system for the elimination of hydrogen gas which comprises a ptetrafluoroethylene-bonded catalyst layer of carbon mixed with platinum black, a porous polytetrafluoroethylene film on the side thereof which faces the gas flow, and a metal backplate, all integrally bonded together. The assembly is particularly useful for the elimination of hydrogen gas in sealed equipment housings, for example, those containing batteries. A similar system may also be used as a detector of hydrogen by utilizing a detector paper therewith which indicates the presence of water.
