has this story on better hydrogen fuel cell technology. From the article
Chemist Don Gervasio and colleague Sonja Tasic, both at Arizona State University in the US, set out to develop a fuel cell that would generate more electricity for its weight than the best batteries, and would also work at room temperature.
Gervasio's solution was to use the alkaline compound borohydride. A 30% solution of borohydride in water actually contains one-third more hydrogen than the same volume of liquid hydrogen.
"The difference is that the borohydride is at room temperature, and it's stable, non-toxic and cost-effective," Gervasio says.
