What is a fuel cell in physics?
A fuel cell may be defined as an electrochemical cell in which the chemical energy of a conventional fuel is converted directly and usefully into electrical energy.
What is a fuel cell easy definition?
A fuel cell is a device that generates electricity through an electrochemical reaction, not combustion. In a fuel cell, hydrogen and oxygen are combined to generate electricity, heat, and water.
What is fuel cell in chemistry class 11?
The galvanic cells in which the energy of combustion of fuels is directly converted into electrical energy are called fuel cells. One of the reactants is fuel such as hydrogen or methanol.
What are fuel cells in chemistry?
fuel cell, any of a class of devices that convert the chemical energy of a fuel directly into electricity by electrochemical reactions. A fuel cell resembles a battery in many respects, but it can supply electrical energy over a much longer period of time.
What is fuel cell classification?
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 Class 12?
The fuel cell is an electrochemical cell in which chemical energy of the fuel is directly converted into electrical energy. It converts the energy from the combustion of fuels such as H2, CO, CH4 etc directly into the electrical energy.
What is fuel cell and its advantages?
(1) The reactants are continuously supplied to the electrodes from the reservoir. Unlike conventional cells, the fuel cells do not have to be discharged when the chemicals are consumed. (2) They are non polluting because the only reaction product is water (for hydrogen-oxygen fuel cell). Video Explanation.
What is fuel cell in chemistry?
A fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat.
What are fuel cells Ncert?
A fuel cell can be defined as an electrochemical cell that generates electrical energy from fuel via an electrochemical reaction. These cells require a continuous input of fuel and an oxidizing agent (generally oxygen) in order to sustain the reactions that generate the electricity.
What is the working principle of fuel cell?
A fuel cell is an electro-chemical device in which the chemical energy of fuel is continuously converted into electric energy. This conversion of energy takes place at constant pressure and temperature.
What’s the purpose of a fuel cell?
Fuel Cell Table of Content. What is a Fuel Cell? Working of Fuel Cell. The reaction between hydrogen and oxygen can be used to generate electricity via a fuel cell. Types of Fuel Cells. Despite working similarly, there exist many varieties of fuel cells. Applications of fuel cell. Fuel cell technology has a wide range of applications.
What type fuel is used in a fuel cell?
– A PEM fuel cell type – Consume about 0.8 Nm3 of hydrogen per kWh produce – Proven durability – Made up of elementary cells – Stacked in series or in parallel circuits – Intensity can be precisely calibrated to the intended use – Hydrogen-powered vehicle or for an autonomous stationary application compatibility
What countries use fuel cells?
Japan.
What happens inside a fuel cell?
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. A fuel, such as hydrogen, is fed to the anode, and air is
