Fujikura products on display for portable fuel cells, passive
Fujikura Japan “FC Expo 2010 International Exhibition of hydrogen,” on the screen for mobile and portable fuel cell laptops. inspiron 2600 battery
Currently used for portable products, DMFC, in most cases, the main purpose is lithium-ion battery. Through the use of lithium-ion rechargeable supplement, which resolved when the gaps to reduce the size DMFC - a power output lower. Therefore be able to cope with time portable quick start and use the power of advanced DMFC is mainly used for extending lithium-ion rechargeable battery drive.
The characteristics of the test products of the business can be conducted through mobile products DMFC (Figure 2). Portable products are just 5 minutes after lighting by lithium-ion battery to drive, then you can directly from the DMFC power generation of electricity to drive. DMFC Company is not necessary to use pumps can be supplied to the power generation part of passive methanol battery. DMFC, the average output power of 4W, the output density of about 100mW/cm2, the highest in the passive DMFC.
Fujikura DMFC production due to the higher density of DMFC as a whole to obtain a high yield, for example,367759-001 , heat generated during the electricity used for fuel. DMFC Company used the concentration of methanol fuel about 50%. Is characterized by the use of internal electronic products such as the use of heat by heat pipe cooling (Heat Pipe) Thermal technology and liquid delivery (Figure 3) so that the supply of methanol after the technology of the evaporation. The principle is to use the heat produced when electricity is on the order of methanol heated to 80 ℃ after evaporation, and then supplied to the power generation part.
The trial, compared with the original product may be a more appropriate pressure on the supply of methanol, you can maintain an average output power at the same time scale down to 1 / 2 approx.
The future development of the policy is to promote implementation of the following two aspects: First, the size of down to be built into the phone, 2 laptops, external battery, the average output power up to 10W or more.
With communication cables, communication cables and electronic components packaging manufacturer Fujikura not know why the DMFC for developing portable products with it? tecra a5 battery , At first sight, now existing there is no correlation. When asked about this issue, Fujikura, said the goal is to become one “with wire and fiber” of the company, why the need to establish new business pillar.
