Hydrogen Purification

A primary challenge to the creation of a hydrogen infrastructure is the purification of hydrogen fuels prior to use by fuel cells. Impurities ranging from carbon monoxide to sulfur may degrade performance of fuel cell systems over time; thus the removal of these impurities prolongs the lifetime of fuel cells. Faculty at the C2E2 represent diverse experience with porous and non-porous membranes constructed from polymeric, metallic, ceramic and cermet materials, for the purpose of purifying hydrogen produced from fuel reforming. Objectives include (i) identifying key mechanisms of hydrogen purification in novel cermet materials as well as investigating electrochemical purification techniques using PEM systems, (ii) maximizing hydrogen purification rates, while (iii) minimizing materials and operations costs.
