Influence of Electrolytes and Membranes on Cell Operation for Syn-Gas Production

Year: 2012

Type: article

Abstract: The impact of membrane type and electrolyte composition for the electrochemical generation of synthesis gas (CO + H 2 ) using an electrolysis cell containing a Ag gas diffusion cathode is presented. Changing from a cation exchange membrane to an anion exchange membrane extended the cell operational time at low cell voltages (E cell ) without impacting product composition. The use of KOH as the catholyte decreased the E cell and resulted in a minimum electrolyte cost reduction of 34%. The prime factor in determining operational time at low E cell was the ability to maintain a sufficiently high anolyte pH.
