Abstract
A direct hydrogen peroxide/proton-donating-fuel fuel cell for production of electric current by reduction of hydrogen peroxide coupled with oxidation of fuel by means of ion transfer across an ion-conducting polymer electrolyte is provided. In addition, a hydrogen peroxide concentration meter is provided, which may be utilized, for example, for measuring the concentration of hydrogen peroxide in solutions that may contain strong electrolytes or in automated systems such as those to be used with the present fuel cell.
Claims33
A direct hydrogen peroxide fuel cell, comprising:
- a first compartment having a first end with at least one input orifice and at least one output orifice disposed therein, and a second open end;
- an anode disposed adjacent and in contact with the second open end of the first compartment;
- an ion-conducting membrane disposed adjacent to and in contact with the anode;
- a cathode disposed adjacent to and in contact with the ion conducting membrane and electrically connected to the anode;
- and
- a second compartment having a first end with at least one input orifice and at least one output orifice disposed therein, and a second open end disposed adjacent to and in contact with the cathode.
