Hydrogen purity or hydrogen quality describes the presence of impurities in hydrogen when used as a fuel gas. Impurities in hydrogen can interfere with the proper functioning of equipment that stores, distributes, or uses hydrogen fuel. Zobacz więcej The impact of impurities varies with the specific equipment used and on the physio-chemical nature of the impurity. For example, hydrogen boilers that combust hydrogen will generally tolerate higher concentrations … Zobacz więcej As the permissible concentrations for many impurities are very low this sets stringent demands on the sensitivity of the analytical methods. Moreover, the high reactivity of some impurities requires use of a properly passivated sampling and analytical … Zobacz więcej • Hydrogen station • Hydrogen fuel • Hydrogen purifier Zobacz więcej The presence of impurities in hydrogen depends on the feedstock and the production process. Hydrogen produced by electrolysis of water may routinely include trace oxygen and water, which must be usually be removed prior to use. Hydrogen … Zobacz więcej See also: Hydrogen purifier Purification of hydrogen is an important aspect of hydrogen distribution and there are a range of technologies available depending on the impurities present and process conditions.

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.
