KDDI fuel cell for mobile phone offers plenty of talk time

I for one really look forward to the day when recharging my notebook or cell phone simply means squirting more fuel into its fuel cell rather than searching for an AC outlet. Fuel cells are coming for sure and a few of them are already on the market like the offering from Medis, though they aren’t quite what most of us want. What I want is a fuel cell like the one KDDI is showing off that is refillable with methanol and runs for up to 320 hours.

Toshiba’s product roadmap leaked

If this is authentic, Toshiba has some interesting products lined up through 2010. Techblog.gr leaked a powerpoint slide of Toshiba's product roadmap featuring a few handheld computers featuring the Qualcomm SnapDragon platform. There were prototypes first demoed at CES earlier this year, and from the looks of it, those prototypes are ending up as real products.

Sony demo hybrid fuel-cell concepts

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.
