Abstract

The key characteristics of a laboratory-scale membrane reformer for high-purity hydrogen production from methane with a 4- $$ \mu $$ m-thick palladium membrane are described quantitatively using a mathematical model for an ideal displacement reactor that takes account of the hydrogen mass flux through the membrane and chemical reaction in the gas phase. Application of model representations for calculating the basic technological and design parameters of a high-efficiency membrane reformer with a 41.8 m 3 H 2 /h production capacity for feeding a 50 kW battery of proton exchange membrane fuel cells (PEMFC) with hydrogen is illustrated on a project example.
