Furthermore, the presented dryer design represents an efficient combination of fuel transport, drying equipment and fuel feeding system.
The results have shown that the system is able to capture the nonlinear feature of the fuel feeding system.
A biomass fuel feeding system has been designed, constructed and evaluated for a fluidized bed gasifier (FBG) pilot plant at the University of Saskatchewan (Saskatoon, SK, Canada).
Different from DMFCs with active fuel feeding systems, passive DMFCs with nearly stagnant fuel and air tend to bear comparatively less power densities.
Vapour lock, partial or complete interruption of the fuel flow in an internal-combustion engine, caused by the formation of vapour or bubbles of gas in the fuel-feeding system.
It was also demonstrated that this passive fuel-feed system could successfully self-regulate the fuel-feed rate in response to the change in discharging currents.
The experimental results showed that with this fuel-feed system, the fuel cell fed with high methanol concentration of 12.0 M yielded the same performance as that of the conventional DMFC running with 4.0 M methanol solution.
To overcome this problem, we propose a new self-regulated passive fuel-feed system that not only enables the passive DMFC to operate with high-concentration methanol solution without serious methanol crossover, but also allows a self-regulation of the feed rate of methanol solution in response to discharging current.
Despite the continuously increasing stock production of dual-fuel (petrol LPG) passenger car models, doubts still exist about both real engine performance in LPG operation and the reliability of the dual-fuel feeding system.
The three different fuels feeding systems, i.e. pure hydrogen, pure hydrocarbons (alcohol, i.e. methanol and ethanol; formic acid and ethylene glycol) and on-board hydrogen from reformed hydrocarbons like methanol or other compound like water can be used for operating the micro-fuel cells.
