Hydrogen Membrane Separation Techniques

Industrial & Engineering Chemistry Research, 2006
About 80% of the present world energy demand comes from fossil fuels. Unlike using fossil fuels, using hydrogen as an energy source produces water as the only byproduct. Use of hydrogen as an energy source could help to address issues related to energy security including global climate change and local air pollution.

Hydrogen separation using electrochemical method

Journal of Power Sources, 2004
Hydrogen is separated from a hydrogen/nitrogen/carbon dioxide mixture by an electrochemical separation method. By applying a direct current to a proton-conducting membrane, hydrogen can be electrochemically dissociated on the platinum catalyst of the anode, transported across the hydrated cation exchange membrane, and then recovered on the catalytic ...

HYDROGEN SEPARATION WITH ELECTROCHEMICAL CELL

Chemistry Letters, 1980
Abstract A new technique for hydrogen separation using a short-circuited electrochemical cell constructed by use of a solid electrolyte was described with preliminary experimental data. With phosphomolybdic acid as a proton conductor, a short-circuit current density of 7.4 mA/cm2 or a rate of hydrogen separation of 3.1 cm3/h·cm2 ...

Industrial membranes for hydrogen separation

2017
Production of hydrogen, as an environmentally benign alternative for fossil fuels that mainly contribute to the growing pollutant emissions, has been considered specifically in the last decades. As a result of being associated with other gases, such as CO2, CO and other impurities, the produced hydrogen must be separated and purified before being ...

Hydrogen separation using LaNi5 films

Journal of the Less Common Metals, 1986
Hydrogen separation has been studied using LaNi5 thin films. Porous stainless steel discs were employed as substrates on which nickel or aluminium was first plated in order to reinforce the durability of the film and then LaNi5 was deposited on the nickel- or aluminium-coated disc by a flash-evaporation method. An H2(80)-C3H8(20), H2(80)-CH4(20), H2(

Electrochemical hydrogen compression and separation

2019
Hydrogen is produced at a large industrial scale primarily from natural gas for heavy- industrial applications (e.g., petrochemical). However, there is a growing global market for merchant hydrogen (relatively small-scale, analytical equipment, fuel cells, microelectronic fabrications, turbine cooling, etc).
