Alternative Title
2 kW Class DMFC Design for Improving Charging and Discharging Characteristic of Electric Vehicles
Abstract
Electric vehicles (EV) are used motor instead of an internal combustion engine. There are many merit such as quiet, easy maintenance and environmental. But disadvantages are long battery charging time due to low-energy density, distance limit of driving, expensive battery prices,
expensive compared to regular cars, heavy weight and environmental issues due to using of commercial power.
Direct methanol fuel cell (DMFC) differs has many merits compared with the conventional type fuel cell as follows; no need of fuel reformer, easy to transport, low price, use liquid duel such as methanol, safer reaction
temperature lower then 80℃. Therefore DMFC is very advantageous power source such as portable, mobile, residential, small and remote discrete demand.
In this theses, we develope a DMFC hybrid electric vehicle that can drive fuel cell and battery powers and test the charging/discharging characteristics of a LiFePO4 battery in DMFC hybrid electric vehicle. For this work, we
design a 2kW class DMFC stack and mount a DMFC system in commercial electric vehicle. We also present the advantages and disadvantages of the DMFC hybrid electric vehicles and invest the driving characteristics using
Labview.
