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 is meant by fuel cell definition?
Wikipedia Definition. A fuel cell is
an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions
. … Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied.
What is fuel cell in chemistry class 12?
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 fuel cell Explain briefly with example?
A fuel cell is
a device that produces electricity through a chemical reaction between a source fuel and an oxidant
. The source fuel could be almost anything that can be oxidized, including hydrogen, methane, propane, methanol, diesel fuel or gasoline. … Fuel cells offer several advantages over conventional power sources.
What are chemical fuel cells?
A fuel cell is
a device that converts the chemical energy from fuel into electricity via a chemical reaction with
oxygen or another oxidizing agent. … Fuel cells are made up of three adjacent segments: the anode, the electrolyte, and the cathode.
What is the principle of fuel cell?
| Fuel Cell Efficiency, %LHV | Fuel Cell Type | 40-45 | 50-60 | 50-60 |
|---|
What is fuel cell and its application?
A fuel cell
produces electricity through a chemical reaction
, but without combustion. It's an electro-chemical energy conversion device that produces electricity, water and heat. The reactions that produces electricity happens at electrodes.
Where is fuel cell used?
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 advantages of fuel cell?
Hydrogen fuel cells are cleaner and more efficient than traditional combustion-based engines and power plants. Hydrogen and fuel cells can also be used in mobile applications to power vehicles and mobile power packs. The benefits of fuel cells are:
Reduced greenhouse gas emissions
.
Are fuel cells the future?
In the future,
fuel cells could power our cars
, with hydrogen replacing the petroleum fuel that is used in most vehicles today. … Unlike a typical battery, which eventually goes dead, a fuel cell continues to produce energy as long as fuel and oxidant are supplied.
What are the main components of fuel cell?
The primary components of a fuel cell are
an ion conducting electrolyte, a cathode, and an anode
, as shown schematically in Fig. 1. Together, these three are often referred to as the membrane-electrode assembly (MEA), or simply a single-cell fuel cell.
How long do fuel cells last?
The fuel cell stacks are designed to last the lifetime of the vehicle,
about 150,000–200,000 miles
. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.
Who invented the fuel cell?
First invented in 1839 by
Welsh scientist William Robert Grove
, the fuel cell wasn't commercially used until the 1960s. As part of Project Gemini — which took part from 1962-1966 — NASA used fuel cells to generate power for probes, satellites and space capsules.
What happens to a fuel in a fuel cell?
A fuel, such as hydrogen,
is fed to the anode, and air is fed to the cathode
. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, which take different paths to the cathode. The electrons go through an external circuit, creating a flow of electricity.
What is the equation for a hydrogen fuel cell?
Overall cell reaction:
2H

+ O
2
→ 2H

. SOFC systems can run on fuels other than pure hydrogen gas.
Is a fuel cell a galvanic cell?
A fuel cell is
an electrochemical device
(a galvanic cell) which converts free energy of a chemical reaction into electrical energy (electricity); byproducts are heat and water/steam if hydrogen and air are the reactants; in some fuel cell types, the additional byproducts may be carbon dioxide and leftover lower forms …
