Abstract: A new fuel composition useful for catalytic fuel cells is made up of at least two components. The primary fuel component is a surface active compound, such as methanol, that is a source of and acts to prevent unwanted decomposition of the auxiliary fuel. The auxiliary fuel is a hydrogen-containing inorganic compound with a high reduction potential, such as NaBH4, which acts as a highly reactive source of energy and serves to catalyze the catalytic oxidation of the primary fuel.

Abstract: A liquid fuel composition useful for catalytic fuel cells is made up of at least two components. The primary fuel component is a surface-active compound, such as methanol, that is a source of and acts to prevent unwanted decomposition of the auxiliary fuel. The auxiliary fuel is a compound having a standard reduction potential more negative than the reduction potential of hydrogen gas, which serves as a source of energy and serves to catalyze the catalytic oxidation of the primary fuel.

Abstract: A fuel cell is provided that is suited for mobile and portable applications. Using an innovative anode with a layer to control the rate of diffusion of fuel to the fuel cell anode, fuel crossover through the liquid or solid electrolyte of the fuel cell is prevented Electrolyte integrity is preserved, giving a more robust and reliable fuel cell. Further, the innovative anode allows for the use of highly active fuel compositions which otherwise may be chemically oxidized, releasing heat, or give unstable electrical currents. The use of active fuel compositions with the anode, as well as a fuel composition and liquid electrolyte in which gaseous side-products dissolve allows for the design of robust, powerful portable fuel cell which can be used at room temperature with little peripheral equipment.

Abstract: A novel method for preparation of electrodes at a low temperature from electroconducting refractory powder materials. The electrodes are useful for analytical purposes. The method is based on cold pressing of the powders, wetted with solution of a polymer and placed into a disposable frame of the same polymer, with the help of a laboratory hand device producing a relatively small pressure. Control of the end of pressing is done by means of measurement of the electrode resistance. A puncheon serves as a current conductor. Electrodes thus prepared have a low resistance, a high sensitivity and stability. In comparison with glassy carbon electrodes, the most widely applied ones in electroanalytical chemistry, the novel electrodes are cheaper, yet not inferior to such glassy carbon electrodes, and even sometimes better.
