Power density up 30% for MTI Micro’s Mobion micro fuel cell technology

MTI MicroFuel Cells has passed a significant power milestone for its Mobion® direct methanol fuel cell engine. The technology has achieved a 30% power density improvement over the performance reported a year ago. This performance level is believed to be the highest power density yet for micro fuel cells for portable electronic devices.

The MTI Micro Mobion direct methanol fuel cell engine has demonstrated a power density of 84 mW/cm2 while maintaining its fuel efficiency of 1800 Wh/kg or 1.4 Wh/cm3. This achievement shows a 30% power density improvement over the 62 mW/cm2 announced last year. This latest improvement furthers MTI Micro’s leadership position in the development of direct methanol fuel cell (DMFC) solutions for the portable electronic devices industry.

‘Having a greater amount of energy in smaller amount of space is always a major concern of customers with power-hungry devices,’ says Peng Lim, president/CEO of MTI Micro. ‘This significant improvement addresses manufacturers’ needs for a compact, power-dense energy supply, while incorporating a simplified design. The new design is engineered to greatly reduce assembly time and cost, to pave the way for high-volume manufacturing.’

MTI Micro’s Mobion micro fuel cell provides full power in any orientation, at any humidity level, and within the operational temperature range of consumer electronic devices. This fuel cell power density improvement marks another milestone in MTI Micro’s developments.
