In this slide show Magneto-Hydro-Dynamic Power Generator and Hydrogen Fuel Cell Energy Source are explained. An experimental case study of implementation of MHD power plant is discussed. Various applications of fuel cells are stated. The graph showing growth in energy generation using Fuel cells is given.

2. Magneto-Hydro-Dynamic power generator
• It generate electric power by
means of the interaction of a
moving fluid (usually an ionized
gas or plasma) and a magnetic
field.

3. Ravichandran et al, “Enhancement of Power Generation in
Thermal Power Plant Using MHD System,” IOSR Journal of
Mechanical and Civil Engineering, 2016
• It was observed that the efficiency of a coal fired thermal power plant is
about 40% and the efficiency of MHD power generation system is about 10-20%.
If this MHD generator is coupled with thermal power plant, the efficiency of the
power plant will be increased up to 60%.
• An attempt has been made to study the systematic analysis and
performance of a magneto hydrodynamic generator equipped with a coal fired
thermal power plant, Tuticorin Thermal Power Station located at thoothukudi
district, Tamilnadu.
• The flue gas coming from the chimney of the plant was taken as the conducting
fluid for MHD generator and performed the experimental program.
• It concluded that, if the proposed MHD Generator is equipped along with the
thermal power plant, the efficiency of the plant will be increased by 10%.

4. Fuel Cell
• A fuel cell is an electrochemical cell
that converts the chemical energy of
a fuel (often hydrogen) and an
oxidizing agent (often oxygen) into
electricity through a pair of redox
reactions.
• Redox reactions are characterized by
the transfer of electrons between
two chemicals
Anode reaction: H2 → 2H+ + 2e−
Cathode reaction: 1/2O2 + 2H+ + 2e− → H2O
