Different Ways To Generate Electricity
Hydrogen Fuel Cell
Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy. Its not a source of energy but an Energy Carrier.
What is Electricity?
The energy sources we use to make electricity
can be renewable or non-renewable, but electricity itself is
neither renewable nor non-renewable.
Electricity travels at the speed of light . That totals more than 186,000 miles every second.
Present sources of
energy
Harnessing The Power Of Hydrogen
Hydrogen ?? What is it ?
Hydrogen gas glows purple when ionized.
I am the lightest element and am gas at normal temperature and pressure. I condenses to liquid at temperatures of -253° Celsius.
Hydrogen ?? What is It ?In Greek, hydrogen means "water-former".
NGC 604, a giant region of ionized
hydrogen in the Triangulum Galaxy
Hydrogen is not a fuel…it is a way of storing and transporting energy , similar to a battery.

But, Why Hydrogen ??
2) CO + H2O → CO2 + H2
Steam reforming
1) CH4 + H2O → CO + 3 H2
Production of H2
Coal Gasification18% of world production.
Byproduct of steel industry. Primarily found in Europe and Asia
The hydrogen contained in a
liter of water can be used to
produce of electricity!
Thermo chemicalSplit water with chemicals and heat Photo electrochemical
Split water using sunlight directly, or using chemicals and heat
BiologicalSplit water using organisms
How to use H2 as fuel ?

Hydrogen Safety
Hydrogen gas leaking into external air may spontaneously ignite. Moreover, hydrogen fire, while being extremely hot, is almost invisible, and thus can lead to accidental burns.
reacts easily with air
The most challenging properties of hydrogen are its high dispersability, its wide explosion limits, low ignition energy and its colourless flame.
the hydrogen sensor detects H2 it shuts off the fuel cell via relay
