Abstract

Provided herein is a low-temperature methane steam reformer comprising a proton-exchanged membrane fuel cell comprising an anode and a cathode, wherein hydrogen is produced at the cathode, wherein the fuel cell comprises a metal- membrane-assembly utilizing platinum electrocatalysts. Also provided are methods of producing hydrogen using the low temperature methane reformer, comprising feeding methane to the low temperature methane reformer at a relative humidity (RH) of 60% to 100%; and catalyzing the reaction at temperature of 30°C and 120°C or less and back pressure of 90 kPa and 1000 kPa or less.
