Question

which electrolyte are used in fuel cell ?
​

Answer 1

Answer:

Potassium hydroxide

Explanation:

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).
