    • 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 CO2 and H2 without leaving any residue. From a bench-top small generator, producing about 1 lb of CO2 per day to a large-scale generator producing 1 ton of CO2 per 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 CO2 generated. Individual cells operate at less than 1.2 volts at current densities in excess of 0.75 amps/cm2. CO2 production 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 CO2 gas cylinders.
    • 系统描述为“现场”生产大量的二氧化碳和氢气。 该系统包括一堆多个电化学电池,其将有机羧化化合物分解成CO2和H2而不留下任何残留物。 从台式小型发电机,每天产生大约1磅二氧化碳到大型发电机,每天产生1吨二氧化碳,这个过程基本上是相同的。 无水或二水合物形式的草酸用于有效地产生气体。 所需的能量低于每千克产生的二氧化碳0.3千瓦小时。 在电流密度超过0.75安培/平方厘米的情况下,单个电池的工作电压低于1.2伏特。 二氧化碳生产率可以通过电压或电流调节进行控制。 由于目前设定了天然气生产率,因此不需要计量。 这些系统可以竞争取代传统的压缩CO2气瓶。

    • A force sensor comprises a fluid-tight housing having two ends and a first wall at a first end. A flexible diaphragm (76) has a contacting surface (78) for transferring an external force to the sensor. The diaphragm is disposed to form a second wall at a second end of the fluid-tight housing and defines a storage chamber therein for holding a supply of electrochemically active gas. A rigidly supported electrolytic membrane (16) having two sides is disposed between the first and second walls to divide the storage chamber (14) into a smaller storage chamber (14) and a sensor chamber (12). At least one pervious electrode (18,20) is disposed on each side of and in contact with said electrolytic membrane (16). The electrodes form at least one electrode pair (18,20) separated by the electrolytic membrane (16). The gas is electrochemically reversibly active so as to enter into an anodic reaction at one side of the electrode pair whereby gas molecules are converted to ions transportable through the membrane (16) and a cathodic reaction at the opposite side of the electrode pair whereby ions are reconverted to gas molecules. Measurement means is provided for measuring the voltage between the electrode pair (18,20) (Fig 8A).

    • A prime mover or motor having a single compartment in which pressure variations are produced by transporting molecules into and/or out of the compartment by means of an electrolytic membrane (310). A device is disclosed for converting the pressure changes to mechanical motion without adversely affecting the sealed condition of the compartment. The mechanical motion produced by the apparatus is typically reciprocating linear motion.
      Disposed within the compartment is an electrochemically active material that can exist in the gaseous phase and that can enter into an oxidation/reduction reaction in order to form ions that move across the electrolytic membrane (310) so as to increase or decrease pressure in the compartment in response to application of a voltage gradient of proper duration and polarity across the membrane. Hydrogen and oxygen are suitable materials for use in the apparatus.
