Fuel cells are clean power sources for both large‐scale and portable applications, as they provide a viable method for converting the chemical energy of fuel directly into electrical energy. The most developed FC is the H 2 ‖O 2 system, which uses hydrogen as fuel. However, there are some issues with the use of hydrogen, such as sourcing, safety of handling, and storage. Direct borohydride fuel cells address some of these concerns. They consist of both fuel, which is oxidized at the anode, and hydrogen peroxide (or O 2 ), which is reduced at the cathode. Their many advantages, such as high theoretical specific energy (up to 17 kWh kg −1 ) and high theoretical cell voltage (up to 3.02 V), have attracted increasing interest. Borohydride is also available in solid state (NaBH 4 ) or as an aqueous electrolyte up to 30 wt%, where it remains with a half‐life of around 270 days at pH 13.9 (25 °C) in a strong alkaline solution. Borohydride FCs can operate under ambient conditions and in an air‐free environment, which makes them convenient for portable and anaerobic applications. The main challenge to their commercialization is the selectivity of the anode catalysts and their substrate materials. Many publications have investigated noble metals (e.g. platinum, gold, palladium) as candidate materials, but none have found yet an anode catalyst able to meet the needs of both high catalytic activity toward oxidation and low activity toward its hydrolysis. Several improving strategies are being investigated.

A technical review of the progress achieved in hydrogen storage materials development through the U.S. Department of Energy's (DOE) Fuel Cell Technologies Office and the three Hydrogen Storage Materials Centers of Excellence (CoEs), which ran from 2005 to 2010 is presented. The three CoEs were created to develop reversible metal hydrides, chemical hydrogen storage materials, and high-specific-surface-area (SSA) hydrogen sorbents. For each CoE, the approach taken is specified, key outcomes and accomplishments identified, and recommendations for future work are suggested. The Metal Hydride Center of Excellence addresses work on destabilized hydrides, including the LiBH/Mg 2 NiH 4 system, borohydrides, amides, and alanes; and compares the best materials to DOE targets. The Chemical Hydrogen Storage Center of Excellence discusses the classes of materials studied for chemical hydrogen storage, focusing on ammonia borane and examines the progress in developing efficient regeneration schemes. The Hydrogen Sorption Center of Excellence describes the progress in developing high-SSA sorbents and pathways for developing improved materials capable of achieving DOE targets. The phenomenon of spillover is also observed and its importance to ensuring improved measurements is discussed. Through the five-year effort of the Hydrogen Storage Materials Centers of Excellence, significant progress was achieved in developing and understanding hydrogen storage materials.
