Abstract

A 28-W direct borohydride–hydrogen peroxide fuel-cell stack operating at 25 ◦C is reported for contemporary portable applications. The fuel cell operates with the peak power-density of ca. 50mWcm−2 at 1V. This performance is superior to the anticipated power-density of 9mWcm−2 for a methanol–hydrogen peroxide fuel cell. Taking the fuel efficiency of the sodium borohydride–hydrogen peroxide fuel cell as 24.5%, its specific energy is ca. 2 kWh kg−1. High power-densities can be achieved in the sodium borohydride system because of its ability to provide a high concentration of reactants to the fuel cell.
