Abstract

To overcome the problems of a current hydrogen storage technology, EnerFuel has invented a proprietary chemical process, which produces hydrogen through a new chemical reaction of sodium borohydride. Based on the new chemistry, EnerFuel developed portable hydrogen storage and generator system. This device has 7.03 kWh total hydrogen content and is designed to provide hydrogen on demand for 1W to 60 W fuel cells. However, the simple system design allows for easy scaling up or down hydrogen content and flow rates. This specific storage is designed to be used on board of a remote surveillance system produced by EnerFuel. The storage operates at low pressure and in a wide temperature range from less than 0{degree sign}C to 80{degree sign}C. A new storage is a safe and reliable supply of hydrogen. The hydrogen is generated and present only when required by fuel cell. As a result of the advanced design, the hydrogen volumetric capacity is 40.8 g/L, and gravimetric capacity is 35.2 g/kg.
