Japanese Rock Valley fuel cell bicycle industry exhibition
Posted By admin on March 9, 2010
Rock Valley fuel cell industry in the exhibition “FC EXPO 2010″ on the show who is the Kansai International Airport, a trial of fuel cell bicycle. There is a luggage rack on top of the back is equipped with a power of 60W class fuel cell solid polymer electrolyte (PEFC) system, the bike you can PEFC side to help the engine power to the rechargeable lithium-ion battery (capacity 26V -4Ah) to recharge while driving. Hydrogen as fuel in the storage of hydrogen filling. In the tank hydrogen storage is full, inspiron 1501 battery , rechargeable lithium-ion battery is fully charged when life a distance of about 45 kilometers (due to different driving conditions). PEFC power generation of about 3 hours.
Constitute the PEFC system, including the reservoir of hydrogen storage tanks for hydrogen storage in coupler (coupler), the right of the storage tank of hydrogen taken out of hydrogen to the relief valve, PEFC, air fans, as well as PEFC DC-DC (direct current – DC) converter (Figure 2 ~ 4). Tank storage of hydrogen using the hydrogen storage alloy to store hydrogen by the way, the internal capacity of 0.25L, can be stored in an atmospheric pressure of hydrogen is equivalent to 80L of 7g. The company said hydrogen storage alloys are titanium-zirconium class, tank hydrogen storage is equipped with 750 g of alloy hydrogen storage.
Coupling only in the vacuum storage tank of hydrogen and vents can be inserted through the valve opens when you insert the structure. Although the proposed regulations by the storage tank of hydrogen removed from the hydrogen pressure can not exceed 1 MPa, although 1MPa high pressure, requiring the provision of hydrogen for the preparation phase of PEFC, through the pressure regulating valve to reduce the hydrogen pressure. PEFC Output Voltage 30 ~ 35V. DC-DC converter with 26V step-down sound, then the lithium-ion batteries. We learn that PEFC system weighs 1.1 kilograms.f2024a, f2024b , Filled with hydrogen in the storage tank of hydrogen, you need to use the “Bomb Store” in the scheme of hydrogen filling special. Kansai International Airport station refueling hydrogen has also been put in place the mechanisms .
Rock Valley industry commentator said that although the output power of 60W class PEFC is not enough. “So that also depends on driving conditions, but sometimes can not keep the power output.” Rock Valley Industries that currently no concrete plans and practical purpose is to improve the output of the PEFC power system. The fuel cell bicycle Japanese Economy,btp-63d1 , Trade and Industry as a “hydrogen fuel cell Empirical Project (JHFC):” Some developed.
