Research project: Development of borohydride fuel cells

Currently Active: 

The Direct Borohydride Fuel Cell (DBFC) is a novel, high energy source system with high specific energy storage. It has attracted academic and industrial interest for its potential applications in portable electronic devices, transportation and underwater vehicles

Over the last twenty years, there has been an increasing interest in the development of direct borohydride fuel cells (DBFCs). The main problem addressed in this project is the use of surfactants and its effect on the hydrolysis of borohydride ions, which generates hydrogen and decreases the energy efficiency and the power density. The project also investigates the influence of anode and cathode materials including three-dimensional and nanostructured electrodes, the electrolyte composition and the operating conditions on the number of electrons released during borohydride oxidation. The cell design and configuration are also considered.
