Abstract
A device as described for the generation of high purity carbon dioxide (CO2) and hydrogen (H2) by electrochemical decomposition of aqueous solutions of liquid and solid organic acids. A d.c. power source is used to apply a pre-selected current to an electrochemical cell, consisting of an ion permeable membrane and two electrodes. The generation rate of CO2 and H2 are continuous and proportional to the applied current; it can be stopped instantaneously by interrupting the current. Small battery operated generators can produce propellant CO2 and H2 to deliver fluids from containers other uses include the creation of anaerobic environments in incubation chambers.
