Hydrogen fuel cells generate electricity through an electrochemical reaction of hydrogen and oxygen without combustion. They work like batteries and can provide power as long as they have a source of hydrogen fuel. A hydrogen fuel cell uses hydrogen as fuel, oxygen as an oxidant, a proton exchange membrane as the electrolyte, and produces only water as a byproduct. It has the potential to be more efficient than combustion engines and emits no harmful emissions. However, hydrogen fuel cells still face challenges related to production, storage and transportation of hydrogen as well as the high cost of platinum catalysts.
Hydrogen fuel cell vehicles are zero emission and run on compressed hydrogen fed into a fuel cell "stack" that produces electricity to power the vehicle. A fuel cell can be used in combination with an electric motor to drive a vehicle – quietly, powerfully and cleanly.

A hydrogen fuel cell vehicle is a vehicle that uses Hydrogen as a source of fuel. Hydrogen vehicles include hydrogen-fueled space rockets, as well as automobiles and other transportation vehicles. The power plants of such vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen in an internal combustion engine, or, more commonly, by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling transportation is a key element of a proposed hydrogen economy.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Asst. Prof. EEdepartment
2. • Simplest element in universe- one proton and one
electron.
• Occurs naturally as a gas.
• Can be used to create energy through combustion or
use in fuel cells.
• Colorless
• Tasteless
• Odorless
• Slightly soluble in water
• Highly explosive
Definition of Hydrogen
3. Definition of Fuel Cell
• Produces electricity through a chemical reaction, but
without combustion.
• Converts hydrogen and oxygen into water.
2H2 + O2 → 2H2O
• Operates much like a battery, except they don’t
require electrical recharging.
• Can generate power almost indefinitely, as long as
they have fuel to use.
4. What is a Hydrogen Fuel Cell?
•Hydrogen fuel cells (HFCs) are a type
of electrochemical cell.
•HFCs generate electricity by reduction
and oxidation reactions within the cell.
•They use three main components, a
fuel, an oxidant and an electrolyte.
•HFCs operate like batteries, although
they require external fuel.
•HFCs are a thermodynamically open
system.
•HFCs use hydrogen as a fuel, oxygen
as an oxidant, a proton exchange
membrane as an electrolyte, and emit
only water as waste.
5. How do they work?
•Fuel (H2) is first transported to
the anode of the cell
•Fuel undergoes the anode
reaction
•Anode reaction splits the fuel
into H+
(a proton) and e-
•Protons pass through the
electrolyte to the cathode
•Electrons can not pass through
the electrolyte, and must travel
through an external circuit which
creates a usable electric current
•Protons and electrons reach the
cathode, and undergo the
cathode reaction
6. Chemistry behind the technology
Oxidation
At the anode of the cell, a
catalyst (platinum
powder) is used to
separate the proton from
the electron in the
hydrogen fuel.
Anode half-reaction:
2H2 4H+
+ 4e-
Eo
= 0.00V
Reduction
At the cathode of the cell, a
second catalyst (nickel) is
used to recombine the
protons, electrons, and
oxygen atoms to form water.
Cathode half- reaction:
4H+
+ O2 + 4e-
2H2O
Eo
= 0.68V
In electrochemistry, the Eo
cell value (energy) of a fuel cell is equal to the Eo
of the cathode half-reaction minus the Eo
of the anode half-reaction. For a
hydrogen fuel cell, the two half reactions are shown above. So to calculate
the energy of one fuel cell, we need to subtract the anode energy from the
cathode energy. For a HFC, the Eo
cell = 0.68V – 0.00V which equals
0.68V
7. Efficiency of Hydrogen Fuel Cell
• If the fuel cell is powered with pure hydrogen, it has the
potential to be up to 80-percent efficient.
• Honda's FCX concept vehicle reportedly has 60-percent
energy efficiency.

certain bacterial species.
• Storage of hydrogen through metal hydride/non-metal
hydride.
• Problems relating to utilization of hydrogen as a fuel,
i.e., developed for certain engines and fuel etc.

these uses are:
•Power sources for vehicles such as cars, trucks, buses and even boats and
submarines
•Power sources for spacecraft, remote weather stations and military technology
•Batteries for electronics such as laptops and smart phones
•Sources for uninterruptable power supplies.
10. Hydrogen Fuel Cell Vehicles
• A hydrogen fuel cell vehicle is a type of electric vehicle that uses a fuel
cell instead of a battery to power the car.
• FCVs have a driving range similar to a vehicle with an internal combustion
engine – 250 to 400 miles per tank of fuel.
• FCVs are commercially available for lease, but hydrogen refueling
infrastructure does not exist yet in most parts of the country.
• California has a few stations in operation, and more under construction.
• Although the cost of hydrogen is more expensive than gasoline on an
energy equivalent basis, because the electric drive system is two to three
times more efficient than an internal combustion.
11. Hydrogen Fuel Cell Vehicles
• The 2015 Toyota Mirai is one of the first hydrogen fuel cell
