Sharp unveil highest-density methanol fuel-cell

By Chris Davies on Thursday, May 15th 2008 No Comments

Sharp Fuel Cell thumb 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.

Looks like MTI Micro have some big-name competition in the fuel-cell business. Sony have unveiled their own hybrid fuel-cell system, and while the concept might be big, the prototype isn’t. In fact, it measures just 5 x 3cm, but is still capable of pumping out up to 3W of power.

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.
