Abstract

This article presents experimental results of an autothermal scaled-down system for H₂ production. Pure atmospheric pressure H₂, separated in situ by Pd-Ag membranes, is produced by steam reforming (SR) of methane, ethanol, or glycerol. Oxidizing the SR effluents in a separate compartment supplies the heat. The oxidation feed is axially distributed to avoid hotspots. The 1.3 L system, comprises 100 cm² of membrane area, and generates H₂ flow rate equivalent to 0.15 kW at an efficiency of ∼25%. This process leads to comparable performance when different fuels are used. A mathematical model, validated by the measurements, predicts that increasing the membrane area relative to the outer surface area will substantially increase the efficiency and power output. This design serves as proof of concept for on-board pure H₂ generators, with flexible fuel sources, and holds a great promise to reduce the need for special H₂ transport and storage technologies for portable or stationary applications.
