Hydrogen Permeation Characteristics of Pd-Cu Membrane in Plasma Membrane Reactor

Hydrogen is an alternative energy source that has the potential to replace fossil fuels. One of the hydrogen applications is as a material for Polymer Electrolyte Membrane Fuel Cells (PEMFC) in fuel cell vehicles. High-purity hydrogen can be obtained using a hydrogen separation membrane to prevent unwanted contaminants from potentially harming the PEMFC components. In this study, we fabricated a plasma membrane reactor and investigated the permeation performance of a hydrogen separation membrane in a plasma membrane reactor utilizing atmospheric pressure plasma. The result showed the hydrogen permeation rate increasing with time as reactor temperature is increased through joule heating. By decreasing the gap length of the reactor from 2 to 1 mm, the hydrogen permeation rate increases by up to 40%. The hydrogen permeation rate increases by 30% when pressure is applied to the plasma membrane reactor by up to 100 kPa. © 2024, Tech Science Press. All rights reserved.
