Operation Of Fuel Cell

FUEL CELLA 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

Tidal Power PlantThe 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.

Tidal Power

Selection Of SiteThe tidal range should be largeThe storage area should be large The site should allow the development of

the necessary plant for reasonable cost

MHD cycle with SteamHeat 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.
