WitrynaAs a hydrogen gas for fuel cells of the polymer electrolyte type, carbon monoxide has to be reduced to an acceptable level, preferably below 10 ppm, otherwise it poisons the rare-metal-based electrocatalyst. Advancement of fuel-cell-based transportation hinges on a workable solution to this problem. 1. Introduction WitrynaTo use the hydrogen, a purification process is necessary to create purified hydrogen gas. Hydrogen pressure swing adsorption (H 2 PSA) is a process that capitalizes on the …
