The document discusses various non-conventional energy sources including solar, wind, fuel cells, and tidal power. It provides details on the operation of fuel cells, which use hydrogen and oxygen to generate electricity through chemical reactions, as well as technologies for capturing tidal energy from ocean tides and tidal stream water movement. The document also lists factors to consider when selecting sites for tidal power installations, such as large tidal range and storage area.

18. Operation Of Fuel Cell

19. FUEL CELL A fuel cell is an electrochemical conversion device. It produces electricity from fuel(on the anode side) and an oxidant(on the cathode side), which react in the presence of an electrolyte. A hydrogen fuel cell uses hydrogen as its fuel and oxygen (usually from air) as its oxidant. An Electrolyte is sandwiched between two electrodes. Oxygen passes through one end and hydrogen from the other and they electrochemically react to generate electricity, water and heat. Encouraged by a catalyst, the hydrogen atom splits into proton and electron, which take different paths to cathode. Proton passes through the electrolyte and electron creates current which can be utilized before it returns to cathode. There it reunites with hydrogen and oxygen to form water

20. Tidal Power Plant The tides offer a source of energy because of the P.E. of the raised tide water or the K.E. of the tidal stream The water on the earth rises and falls due to changing gravitation force.

22. Tidal Power Assistant

23. Tidal Power

24. Selection Of Site The tidal range should be large The storage area should be large The site should allow the development of the necessary plant for reasonable cost

29. MHD cycle with Steam Heat Energy to Electric Energy. Ionized gas is collected my metallic collecting plates. Fuel with seed(Potassium which increases conductivity of gas) is introduced to the burner. Magnet deflects some of the ions to the plate which gets charged and produce a DC electric potential.
