Disclosed herein is a method for generating hydrogen through the electrolysis of water or aqueous solutions, wherein a cathode material is used which binds hydrogen to its surface in a potential range which is more positive than the reversible hydrogen potential, or which incorporates the hydrogen into its crystal lattice; subsequently, the bound hydrogen is liberated from the cathode material through supply of thermal energy.

Method for the generation of hydrogen

A device for measuring sugar concentration, particularly in a body liquid, for example, blood of a patient is characterized in that an electrochemical glucose cell is used to produce an electrical signal corresponding to the sugar concentration.

Device for measuring sugar concentration

A method for determining the concentration of carbon monoxide in the air along with a measuring electrode for carrying out the method in which the degree of inhibition of an electrochemical reaction caused by the carbon monoxide, in particular the inhibition of a cathodic oxygen reduction, is determined. Preferably the measurement is made with the electric potential held constant and the change in current taking place during inhibition used as a measure of concentration.

Method and apparatus for measuring the concentration of carbon monoxide

An improved heart pacemaker of the type which includes a stimulating electrode and a counter electrode, a pulse generator and which has an implantable glucose/oxygen biofuel cell as an energy supply, in which pacemaker the area of the glucose electrode of the biofuel cell is made larger than that of the stimulating electrode and the stimulating electrode is in electrically conductive connection with the glucose electrode and thus at the same potential.
