Which electrolyte is used in fuel cell?
Answers
Answer:
Potassium hydroxide:-
Alkali fuel cells operate on compressed hydrogen and oxygen. They generally use a solution of potassium hydroxide (chemically, KOH) in water as their electrolyte. Efficiency is about 70 percent, and operating temperature is 150 to 200 degrees C, (about 300 to 400 degrees F).

Potassium hydroxide.
Explanation:
A fuel cell is an electrochemical system combining hydrogen and oxygen to generate energy, with the by-products of water and heat. A single fuel cell, in its simplest form, consists of two electrodes-an anode and a cathode with an electrolyte in between. Hydrogen interacts with a catalyst at the anode, producing a positively charged ion and an electron that is charged negative
SOFCs use the electrolyte as a rigid, non-porous ceramic material. Since the electrolyte is solid, the cells do not need to be constructed in the platelike structure typical of other types of fuel cells. It is estimated that SOFCs will be about 50%-60% effective when converting fuel to electricity.
