Deepakkumar Yadav Phosphoric Acid Fuel Cells (PAFC) A schematic diagram of phosphoric acid fuel cell is shown in Figure. It was developed in 1980s. It uses either pure hydrogen or rich hydrogen gas as fuel and oxygen or air as oxidant. The concentrated phosphoric acid (H3PO4) is used as electrolyte. It is a medium temperature type of … Read more
Classification of Fuel Cells The fuel cells can be classified as follows : Fuel cells classified based on type of electrolyte : Alkaline fuel cell (AFC) Phosphoric acid fuel cell (PAFC) Molten carbonate fuel cells (MCFC) Solid oxide fuel cells (SOFC) Proton/polymer exchange membrane fuel cells (PEMFC) Fuel cells classified based on type of fuel and … Read more
Principle of Operation of Fuel Cells As stated above, a fuel cell is an electro-chemical device in which the chemical energy of fuel is continuously converted into electric energy. This conversion of energy takes place at constant pressure and temperature. For explaining the principle of operation of fuel cells, here we shall considera hydrogen (H2)-oxygen … Read more
Advantages of Fuel Cells Over Conventional Power Plants It is quite in operation and less polluting. Energy conversion efficiency into electrical power is higher. No cooling water needed. Heat generated can be rejected directly to atmosphere, the process being isothermal. Fuel cells can be installed at the point of use thus reducing the power losses … Read more
Introduction of Fuel Cell Fuel cell technology is the new emerging technology. The development of this technology has started only few decades back and it is still under development for its commercial and economical use. A fuel cell is defined as an electrochemical device that continuously converts the chemical energy of fuel into electricity and … Read more
Wind Energy Conversion System (WECS) In earlier times, wind mills were used to lift water for land drainage and to grind grains. But now a days, all over the world the focus is to produce electrical power by using wind energy conversion devices. These are also called as wind turbines (WT) or wind turbine generators … Read more
Design Considerations in Blade Design The blades of a wind turbine are designed based on the forces caused by the rate of change of momentum theory, such blades are not efficient on account of boundary layer separation from blade surfaces. It causes the loss of pressure due to formation of eddies with distortion of flow. … Read more
Wind Diesel or Wind Gas Turbine Hybrid System In remote areas where wind conditions are favourable for generation and there’s non-availability of pied, the hybrid system for small and medium power systems with diesel engine, generators or gas turbine generators can be installed. The wind turbine generator and diesel generator can be connected in parallel. … Read more
Standalone System with AC and DC Loads This system can be used to power AC as well DC loads shown by an schematic diagram in Figure A. Such a system needs an inverter also to convert DC power in AC power.
Wind Energy Conversion System for Battery Charging/DC Loads (Grid Independent System) Such a system is shown in Figure. In this system the wind energy is converted to DC power by a DC generator and charges the batteries. Power is supplied to DC loads or by the batteries. The charge controller is used for controlling the … Read more
