Introduction

There was a power point presentation on Hydrogen fuel, Hydrogen production using electrolyzer and solar energy and solar energy.Topics like Alternative Energy Systems, Renewable Energy Resources were discussed. The teachers were asked about their view of the alternative energy systems (Solar energy, Tidal energy, geothermalenergy, Wind energy).

Laterthere was a detailed description of hydrogen production, and also about how the solar-hydrogen cycle runs. Major components and reactions in anelectrolyzer are shown it's because the teachers will be dealing with this equations in the future classes. One of the types of the electrolyzer i.e.  PEM electrolyzer and the basic operation of the electrolyzer are shown. At the end of the morning session there was a discussion about how to store the hydrogen. The teachers came up with different ideas about how to store the hydrogen. Basically there were three major ways of storing the hydrogen which were discussed by the professor.

Related manuals are supplied to them and now they are ready to conduct the activity#1. The first experiment is hydrogen production using Electrolysis with solar energy. Discussions about the implementation of using hydrogen as a fuel for the cars were conducted. Few cars which use hydrogen as a fuel were shown. Later the professor had brought up some websites, videos related to bloom energy. Fuel cell types, like on what basis they are classified were discussed. Fuel cell types are classified based on electrolyte type and operating temperature. Different types of fuel cells (PEMFC, Alkali fuel cell, phosphoric acid .Fuel cell, molten carbonate fuel cell and solid oxide fuel cell) are discussed in detail. There are many applications like large scale stationary power generation, small scale power and heat generation, propulsive power generation for transportation vehicle. Challenges for fuel cell commercialization are discussed,like to improve cell design and efficiency, increase operating current and power density, reduce the cost, increase reliability and durability of the cell. Disadvantages of the fuel cells are higher ohmic losses, restrictions.Demonstration on fuel cell components and stacks. General safety precautions about operating the fuel cell are discussed. The safety precautions include wearing protective goggles; the units must not be operated when empty, always ensure that they contain sufficient water.
