TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Cell: The electrochemical cell contains a proton exchange electrolyte membrane. The proton exchange membrane is selected from sulfonated tetrafluoroethane copolymer and poly benzyl immidazole. The electrochemical cell contains a proton exchange electrolyte membrane.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The hydrogen production process is selected from stream reforming, carbon dioxide reforming, methanol reforming, and partial oxidation. The increased hydrogen output comprises hydrogen from the pressure swing adsorption unit and the electrochemical cell. The synthesis gas is fed to the pressure swing adsorption unit. The synthesis gas stream is produced by the hydrogen production process. The synthesis gas stream is fed to a water gas shift reactor. The synthesis gas stream is cooled prior to being fed to the water gas shift reactor. The high pressure hydrogen product stream is at a pressure of 10-30 bar. The carbon dioxide is recovered from the waste gas stream. The carbon dioxide is recovered from the waste gas stream by feeding the waste gas stream to a carbon dioxide recovery process that involves compressing the waste gas stream, drying the waste gas stream, cooling the waste gas stream and feeding the waste gas stream to a stripper column with a condenser temperature of -20 to -55 degrees C. The waste gas stream is recovered from the electrochemical cell. The pure liquid carbon dioxide is produced from the bottom of the stripper. The vent gas from the stripper is fed to the hydrogen production plant as a fuel gas. The reformer operation is selected from steam and carbon dioxide reforming. The method (M1) further involves feeding the synthesis gas mixture to a water gas shift reactor prior to feeding to the pressure swing adsorption unit. The synthesis gas mixture is fed to the pressure swing adsorption unit at a pressure of 10-30 bar and a temperature of 15-50 degrees C. The pressure swing adsorption unit contains greater than or equal to 2 beds, and operates at a pressure of 10-30 bar. The low pressure synthesis gas mixture is at ambient pressure. The hydrogen from the pressure swing adsorption unit is recovered at a pressure of 10-30 bar. Preferred Composition: The low pressure waste gas stream comprises hydrogen, carbon monoxide, methane, carbon dioxide, water and trace constituents. The waste gas stream contains 70-80% carbon dioxide. The synthesis gas stream is from a reformer operation. The hydrogen in the waste gas stream is 20-50% of the remainder of the synthesis gas mixture. EXAMPLE - No suitable example given.
