Sony demo hybrid fuel-cell concepts

Sony has been demonstrating a number of fuel-cell concepts, ranging from portable power units to rechargers and even home speaker systems that have their own methanol power-source.  Of most interest are the two devices seen here, which may look like retro radios but in fact combine a rechargeable Li-Ion battery with a methanol fuel-cell.

Fuel-cell powered Toshiba device could be on sale by Christmas?

Toshiba has suggested that it may release a commercial product using a fuel-cell for power before Christmas 2008, ahead of the company's own March 2009 target for such a device reaching the market.  In an interview with Register Hardware, Toshiba's European General Manager for Computer Systems Marketing and Business Development, Thomas Teckentrup, revealed that it should only be "a few more months before everything comes together".

Canon DSLR fuel-cell patent; is MTI Micro their hardware partner?

Canon DSLR fuel-cell patent; is MTI Micro their hardware partner?

Canon have filed a patent that describes a compact fuel-cell system primarily intended for DSLR cameras but that has potential for inclusion in other portable electronics.  The filing details the company's solution to dealing with variances in load currents, an issue in applications such as DSLRs where sudden surges in power draw are frequent.  It uses a number of individual fuel cells combined, with a DC-DC converter that combines the voltages as required.

Sharp unveil highest-density methanol fuel-cell

Sharp unveil highest-density methanol fuel-cell

Sharp have announced the development of a prototype direct methanol fuel cell (DMFC) that it claims achieves the world's highest power density. The cell is constructed of a stack of multiple reed-shaped thin cells, sandwiched together with similarly shaped porous spacers. That increases surface area and maximises air-flow (essential for the fuel cell to produce power), resulting in 0.3W/cc power density.

Fuel-cell powered GPS prototype promises 60hrs continuous use

Fuel-cell powered GPS prototype promises 60hrs continuous use

MTI Micro are demonstrating the latest version of their portable fuel-cell technology, in the shape of a GPS reference design prototype.  Powered by the company's Mobion fuel-cell, which relies on easily exchangeable methanol packs, MTI Micro are claiming the system provides up to three times as much energy as in a typical GPS with four AA batteries.  In the case of this particular design, one fuel-cell manages up to 60 hours of continuous use.
