A model connecting the weight, volume, and chemical changes of heterogeneous borohydride fuel occurring at discharge of the direct borohydride fuel cell is presented. The experimental data measured with a fuel on the basis of water-alkaline solution of potassium borohydride KBH4 at temperature 25°C arc compared with theoretically calculated curves. Good conformity is acknowledgement of the 8-electron mechanism of borohydride ion oxidation.
