Hydrogen production using micro-membrane reactors or membrane microreactors (MMRs) is a significant component of membrane reactor research. The recent progress of three types of MMRs such as hollow-fiber, microchannel, and monolithic MMRs are reviewed using specific examples. The representative application of MMRs as fuel processors for proton exchange membrane fuel cells are summarized in detail. In addition, the modeling progress about MMRs is also briefly introduced.
