▎ 摘　　要

NOVELTY - Electrochemical reactor (100) comprises a mixed-conducting membrane, where the membrane comprises an electronically conducting phase and an ionically conducting phase. The reactor is capable of reforming a hydrocarbon electrochemically. The electrochemical reforming reactions involve the exchange of an ion through the membrane to oxidize the hydrocarbon. The electrochemical reactor comprises a porous anode and a porous cathode that comprise metallic phase and ceramic phase. The metallic phase is electronically conductive. The ceramic phase is ionically conductive. The anode and the cathode have no current collector attached. The anode and the cathode are separated by the membrane and the anode is exposed to a first reducing environment and the cathode is exposed to a second reducing environment. USE - The electrochemical reactor is used in petroleum and chemical industries for large amounts of hydrogen used in upgrading fossil fuels of ammonia or metol or hydrochloric acid plants. ADVANTAGE - The electrochemical reactor: is capable of reforming a hydrocarbon electrochemically, where the electrochemical reforming reactions involve the exchange of an ion through the membrane to oxidize the hydrocarbon; utilizes the anode that promotes electrochemical hydrocarbon reforming reactions; and utilizes the porous anode and the porous cathode that comprise metallic phase and ceramic phase, which are electronically conductive and ionically conductive, and have no current collector attached. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a reactor; and a method for producing hydrogen. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an electrochemical reactor. 100Electrochemical reactor 101First electrode 102Second electrode 103Membrane 104Fuel 105Steam 106Syngas
