What are the applications of the fuel cells?
What are the applications of the fuel cells?
Fuel cells can be used in a wide range of applications, including transportation, material handling and stationary, portable, and emergency backup power. Hydrogen can be used in fuel cells to generate power using a chemical reaction rather than combustion, producing only water and heat as byproducts.
What are the 6 different types of fuel cells?
Types of Fuel Cells
- Polymer electrolyte membrane fuel cells.
- Direct methanol fuel cells.
- Alkaline fuel cells.
- Phosphoric acid fuel cells.
- Molten carbonate fuel cells.
- Solid oxide fuel cells.
- Reversible fuel cells.
What is fuel cell technology?
A fuel cell is an electrochemical energy conversion device that was invented in 1839 by William Grove to produce electricity by combining hydrogen and oxygen into water. Like batteries, fuel cells convert potential chemical energy into electrical energy and generate heat as a by-product.
What is fuel cell with example?
Comparison of fuel cell types
| Fuel cell name | Electrolyte | Efficiency |
|---|---|---|
| Cell | ||
| Proton-exchange membrane fuel cell | Polymer membrane (ionomer) | 50–70% |
| Redox fuel cell (RFC) | Liquid electrolytes with redox shuttle and polymer membrane (ionomer) | |
| Phosphoric acid fuel cell | Molten phosphoric acid (H3PO4) | 55% |
What is fuel cell BYJU’s?
A fuel cell can be defined as an electrochemical cell that generates electrical energy from fuel via an electrochemical reaction.
What are advantages of fuel cell?
Fuel cells can have an efficiency of over 80 per cent, compared to internal combustion engines that currently operate at around 25 per cent efficiency and power plants at about 35 per cent. This is a huge increase in efficiency and shows that the power going in is creating much more energy.
What is the best fuel cell technology?
Alkaline Fuel Cells Operating at 60-70ºC (140-158ºF), AFCs are among the most efficient type of fuel cells, reaching up to 60% efficiency and up to 87% combined heat and power.
What is fuel cell Mcq?
MCQs on Fuel Cell. Fuel cell is an electrochemical cell, which can convert energy from the combustion of fuel such as hydrogen, methanol, etc. directly to electrical energy. Fuel cells require a continuous source of fuel and oxygen and can therefore produce electricity continuously.
What are the characteristics of fuel cell?
A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode.
What is fuel cell limitations?
Expensive to manufacture due the high cost of catalysts (platinum) Lack of infrastructure to support the distribution of hydrogen. A lot of the currently available fuel cell technology is in the prototype stage and not yet validated. Hydrogen is expensive to produce and not widely available.
Why was fuel cell invented?
In 1839, the first fuel cell was conceived by Sir William Robert Grove, a Welsh judge, inventor, and physicist. He mixed hydrogen and oxygen in the presence of an electrolyte and produced electricity and water. The invention, which later became known as a fuel cell, didn’t produce enough electricity to be useful.
Who invented fuel cells in 1839?
Sir William Robert Grove
Sir William Robert Grove, (born July 11, 1811, Swansea, Glamorgan, Wales—died August 1, 1896, London), British physicist and a justice of Britain’s High Court (from 1880), who built the first fuel cell in 1842 and first offered proof of the thermal dissociation of atoms within a molecule.
What are electrochemical applications?
Electrochemical cells are used in torches, digital watches, military applications, corrosion protection, etc. The production of high-purity lead, zinc, aluminum, and copper involves the use of electrolytic cells. They use it to analyze a solution for trace amounts of metal ions.
How do fuel cells work?
Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte.
What is the history of fuel cell technology?
successfully developed a 5 kW st ationary fuel cell. In 1955, membrane as the electrolyte. Three years later another GE sary hydrogen oxidation and oxy gen reduction reactions. GE its use during Project Gemini. This was the first commercial use of a fuel cell.
What are the applications of residential fuel cells?
Residential fuel cell applications may be divided in the following categories: Here the fuel cell is used to provide electric power only for example during power outages or as a part of power management system. Electricity and heat provided by the fuel cell are used simultaneously on site.
What are the basic principals of a fuel cell?

Are fuel cells a viable energy source for smart grids?
In the recent years, microgrid has been receiving increasing attention as one typical structure in smart grid frameworks. Fuel cells (FC) among other most relevant renewable energy sources have been studied as viable energy alternatives, in terms of them being cleaner and more efficient.
