What is the fuel in the combustion reaction that takes place in every cell in your body?
Glucose.
What is the chemical reaction that takes place when oxygen combines with a combustible at a suitably high temperature?
The reaction is usually considered an oxidation-reduction reaction, and that's what we see in combustion, or fire. In a fire, fuel is combusted, and the fuel is oxidized in the process.
What is the main fuel source for work of the cell?
The main fuel source for the work of the cell is the mitochondria.
How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
What can fuel the chemical reactions in a cell?
chemical energy
What are the two gases used to produce electricity in fuel cells?
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
How do fuel cell works?
The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions.The electrons flow out of the cell to be used as electrical energy. The hydrogen ions move through the electrolyte membrane to the cathode electrode where they combine with oxygen and the electrons to produce water. Unlike batteries, fuel cells never run out. In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.

Is Daniell cell a fuel cell?
The Daniell cell (Daniel cell) was invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode. As such it is more akin to a battery than a fuel cell.
What is remarkable about fuel cells?
The only thing that comes out of the tailpipe is water! The other not so remarkable thing is the price. A fuel cell is made up of two electrodes, and each one is an ion-transfer membrane (allows ions to pass through but not air or liquid). In between these membranes is a liquid called electrolyte, whose job is to carry ions from one electrode to the other. On the far side of the cathode (negatively charged electrode), hydrogen is pumped in, and on the far side of the anode (positively charged electrode), oxygen or air is pumped in. At the cathode, hydrogen is stripped of its electrons, which get removed by the electrode. This electricity is used to power lights, ovens, computers, etc.. The remaining hydrogen ions flow through the electrolyte and converge on the anode. On the return trip the electrons get fed into the anode where they are picked up by oxygen atoms, which then combine with the hydrogen ions to form water. Viola, you have a fuel cell. The reason they are so expensive is because, at the anode, a catalyst such as platinum has to be used to help the reaction along. The other issue that is preventing widespread use of the fuel cell is that an effective hydrogen distribution system is not in place. You could have a fuel cell car, but where would you buy hydrogen?

What is a Hydrogen Fuel Cell?
Hydrogen fuel cells are very similar to batteries. They use a chemical reaction between atoms to produce their energy. •It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.
How is a fuel cell different from a typical cell?
A fuel cell oxidizes a fuel source, a standard cell is an electrochemical reaction.
What is the chemical reaction that takes place when oxygen combines with a combustible at a suitably high temperature?
The reaction is usually considered an oxidation-reduction reaction, and that's what we see in combustion, or fire. In a fire, fuel is combusted, and the fuel is oxidized in the process.
What types of material can a fuel cell be made of?
There are 3 main types of a Fuel Cell. 1. Hydrogen Fuel Cell. This is the main one people use nowadays. 2. Solid Oxide Fuel Cell. 3. Alkaline Fuel cell. Made from Alkaline metals.
