Q45. In hydrogen fuel cell, the reactants are bubbled through which electrodes?

Q: What is the correct answer for CUET UG Chemistry Q45?

The correct answer is d. In a hydrogen-oxygen fuel cell:- The reactants, hydrogen and oxygen gases, need to be efficiently brought into contact with the electrolyte and the catalytic sites for the electrochemical reactions to occur.- **Porous carbon electrodes** are typically used. These electrodes are made porous to allow for the effective diffusion of gases to the reaction sites.- These porous carbon electrodes ar

Q45. In hydrogen fuel cell, the reactants are bubbled through which electrodes?

FirstInTest · Accepted Answer

In a hydrogen-oxygen fuel cell:-   The reactants, hydrogen and oxygen gases, need to be efficiently brought into contact with the electrolyte and the catalytic sites for the electrochemical reactions to occur.-   **Porous carbon electrodes** are typically used. These electrodes are made porous to allow for the effective diffusion of gases to the reaction sites.-   These porous carbon electrodes are often impregnated with **catalysts** (like finely divided platinum or palladium) to increase the rate of the electrode reactions.While platinum is a catalyst often used, the primary material for the electrode structure itself to allow gas flow is porous carbon. Saturated calomel electrode and silver electrodes are standard reference electrodes or specific purpose electrodes, not typically used for gas reactant delivery in fuel cells.

Answer

Answer

Silver electrodes

Answer

Platinum electrodes
