Looks like RIM is more interested in fuel cell technology than we thought: the BlackBerry maker has just applied for two closely related patents for including a fuel cell in an electronic device, one for the frame and one for the fuel tank itself. Although the primary aim of either patent is to show how to fit a fuel cell into the tight space of a mobile gadget, they do show a more rectangular and modern device chassis than the last patent we saw, which had more than a slight whiff of the classic BlackBerry about it. Neither application is necessarily a roadmap for the future, and they don't mean your next BlackBerry smartphone will need top-ups of lighter fluid or methanol every few weeks. Still, they hint that fuel cells are at least somewhat more than a passing fancy in Waterloo.
