Evaluation of an Alkaline Fuel Cell for Multi- Fuel System
The performance of an alkaline fuel cell is investigated using three different fuels, e g., methanol, ethanol and sodium borohydride. Pt/C/Ni was used as anode whereas Mn/C/Ni was used as standard (Electro-Chem-Technic, UK) cathode for all the fuels. Thus, the alkaline fuel cell is used for multi-fuel system. Fresh mixture of electrolyte, potassium hydroxide (5M), and fuel (2M) was fed to and w...
متن کاملThe cost of domestic fuel cell micro-CHP systems
Numerous academic and industrial estimates place the cost of a future mass-produced small stationary fuel cell system at around $1,000 per kW, which compares well with targets set by agencies such as the US Department of Energy. Actual sale prices for domestic microgeneration systems do not fit so neatly with these targets, and are currently 30–50 times higher, even though mass production began...
متن کاملA Double Pipe Heat Exchanger Design and Optimization for Cooling an Alkaline Fuel Cell System
In the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (AFC) (which the electrolyte has cooling role of system) has been considered. Proper control volumes of system with specific qualification have been chosen. Consequently, heat and mass transfer in control volumes have been assessed. Considerations on them and contributed models lead to approve a double tube heat...
متن کاملElectromechanical aspects of a micro-CHP system
Solutions Efficient operation of the gas turbine imposes the demand for very high rotational speed of the generator 240,000 rpm. The permanent magnet machine has been chosen as the generator type since this technology is the most promising for high-speed machines: it offers high efficiency and very high power density at low volumes. A high-frequency power converter is required to enable bi-dire...
متن کاملPerformance assessment of a hybrid fuel cell and micro gas turbine power system
In this paper, a hybrid solid oxide fuel cell (SOFC) and micro gas turbine (MGT) power system is parametrically studied to evaluate the effect of different operating conditions. The SOFC/MGT power system includes SOFC reactor, combustion chamber, compressor and turbine units, and two heat exchangers. The effects of fuel utilization, temperature, and pressure are assessed on performance of t...
