The equation to calculate the voltage of a fuel cell is given by:
Vcell = E°cell - (RT/nF) ln(Q)
where Vcell is the cell potential, E°cell is the standard cell potential, R is the gas constant, T is the temperature in Kelvin, n is the number of moles of electrons transferred in the cell reaction, F is Faraday's constant, and Q is the reaction quotient.

What is the word and symbol equations for the reaction of hydrogen and oxygen in a fuel cell?
oxygen and hydrogen makes electricity and water
Which voltage source convert chemical energy to electrical energy?
A battery or fuel cell is a voltage source that converts chemical energy into electrical energy. In a battery, chemical reactions inside the cells release electrons, creating an electric current. In a fuel cell, hydrogen and oxygen react to produce electricity, with water as the main byproduct.
How do you test fuel cell?
Fuel cells can be tested by monitoring factors such as voltage output, temperature, pressure, and fuel flow rate. Performance tests can be conducted under various operating conditions to evaluate efficiency and stability. Additionally, performing a visual inspection of the fuel cell components can help identify any signs of wear or damage.
What is the word equation for the reaction between Fuel and Oxygen?
The word equation for the reaction between fuel (such as hydrocarbons) and oxygen is: fuel + oxygen → carbon dioxide + water + heat.
Is a fuel cell a secondary cell?
No, a fuel cell is not considered a secondary cell. Fuel cells generate electricity through a chemical reaction involving a fuel source and an oxidizing agent, without the need for recharging like secondary cells, such as batteries.

How nearnst equation is useful for calculation of electrode potential?
The Nernst equation is essential for calculating the electrode potential of an electrochemical cell under non-standard conditions. It relates the cell potential to the standard electrode potential, temperature, and the concentrations of the reactants and products involved in the electrochemical reaction. By using the Nernst equation, one can determine how changes in concentration affect the voltage, thereby predicting the behavior of the electrochemical system under varying conditions. This is crucial for applications in batteries, fuel cells, and corrosion studies.
Is a fuel cell producing a current that is alternating or direct?
A fuel cell produces direct current (DC). This is because the electrochemical reactions occurring within the fuel cell generate a steady flow of electrons in one direction, resulting in a constant voltage output. Unlike alternating current (AC), which periodically reverses direction, the output from a fuel cell remains constant as long as it is operating effectively.
Which voltage source convert chemical energy to electrical energy?

What is open circuit voltage in a Fuel Cell?
A: All batteries will eventually fail when that occurs the voltage out of then can be zero or higher voltage when new, In that case the battery has failed but if you measure the output it will have a higher voltage because there is no load or open circuit as soon as the load is applied the voltage just disappear this condition is called open circuit voltage
