Question

What is the source of electrical energy in galvanic cell?

Answer 1

An electrochemical cell is a device that uses two electrodes to carry out electron-transfer reactions that force electrons to travel on a wire that can be used as a source of electrical energy.

Answer 2

$\huge\mathfrak\color{blue}{Answer}$

Spontaneous redox reaction is the source of electrical energy in galvanic cell. Or we can say that Galvanic cell is used to convert chemical energy of a spontaneous redox reaction into electrical energy
