Suggest two materials other than hydrogen that can be used as fuels in fuel cells.

For the electrochemical cell,$M|M^{+}||X^{-}|X$,${E^{o}}(M^{+}/M) = 0.44 \ V$ and ${E^{o}}(X/X^{-}) = 0.33 \ V$. From this data,one can deduce that:

Give advantages of fuel cell.

Give the anodic,cathodic,and overall reactions of a hydrogen-oxygen fuel cell.

Write reactions for the followings :
$1.$ Anode reaction of dry cell.
$2.$ Reduction reaction of dry cell.

Which of the following statements is correct? $A$ galvanic cell converts:
