Abstract
Systems are described for the 'on-site' production of substantial amounts of carbon dioxide and hydrogen. The systems include a stack of multiple electrochemical cells, which decompose organic carboxylated compounds into COand Hwithout leaving any residue. From a bench-top small generator, producing about 1 lb of COper day to a large-scale generator producing 1 ton of COper day, the process is essentially identical. Oxalic acid, either anhydrous or in its dihydrate form, is used to efficiently generate the gases. The energy required is less than 0.3 Kilowatt-hours per lb of COgenerated. Individual cells operate at less than 1.2 volts at current densities in excess of 0.75 amps/cm. COproduction rates can be controlled either through voltage or current regulation. Metering is not required since the current sets the gas production rate. These systems can competitively replace conventional compressed COgas cylinders.
