Patent ID: 8377606

Claim:
A process to generate an electrical current comprising: feeding to the anode compartment of a fuel cell comprising an anode compartment and a cathode compartment and hermetically sealed there between an electrolytic proton conducting ceramic membrane consisting essentially of: BaCe 0.85-e Hf e L f Y 0.05-0.25 O (3-δ) Hf, e is from 0.1 to 0.5, L is a lanthanide and f is from 0 to 0.25 and δ is the oxygen deficiency in the ceramic at a temperature from 500° C. to 900° C. a gaseous stream comprising at least 75 weight % of one or more C 2-8 alkanes and removing from the anode compartment a stream comprising unreacted alkane feed one or more corresponding C 2-8 alkenes and isomers thereof, feeding to the cathode compartment of said fuel cell a gaseous stream comprising at least 20 weight % of oxygen and removing from the cathode compartment unreacted cathode feed and water.
