Abstract
A direct hydrogen peroxide fuel cell for stable and efficient production of electric current by direct reduction of hydrogen peroxide via a cathode comprising a metal phthalocyanine electrocatalyst, 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.
