Title: Methods for producing hydrocarbon products and hydrogen gas through electrochemical activation of methane

Patent ·
OSTI ID:1998450
; ; ;

A method of forming a hydrocarbon product and hydrogen gas comprises introducing CH4 to a positive electrode of an electrochemical cell comprising the positive electrode, a negative electrode, and a proton-conducting membrane between the positive electrode and the negative electrode. The proton-conducting membrane comprises an electrolyte material having an ionic conductivity greater than or equal to about 10−2 S/cm at one or more temperatures within a range of from about 150° C. to about 600° C. A potential difference is applied between the positive electrode and the negative electrode of the electrochemical cell to produce the hydrocarbon product and the hydrogen gas. A CH4 activation system and an electrochemical cell are also described.
