MATIERE ABSORBANT L'HYDROGENE POUR LES CELLULES ELECTROCHIMIQUES

摘要

Buildup of unreacted hydrogen gas in sealed electrochemical cells has been prevented by inserting a hydrogen absorbing device into the cell before sealing. This hydrogen absorbing device is preferably a discrete shaped body, e.g., cylindrical or ring shaped, encased in an electrolyte impermeable, but hydrogen gas permeable membrane and includes a material which will react chemically with hydrogen gas, a catalyst for the hydrogen consuming reaction, and a compatible binder which maintains the reactant and catalyst in the form of a discrete shaped body which is porous to hydrogen gas.
