Abstract
Methods for producing hydrogen gas from organic substances. According to the methods, hydrogen is produced from an electrochemical reaction of an organic substance with water or a base. The instant methods permit the production of hydrogen at lower operating voltages or lower operating temperatures relative to water electrolysis. Operable organic substances include alcohols, ethers, carboxylic acids, aldehydes, and ketones. In a preferred embodiment, hydrogen gas is produced from an electrochemical reaction of methanol in the presence of a base such as NaOH or KOH.
