For a redox reaction to be spontaneous, the standard cell potential (cell) must be positive.

The reduction half-reaction of a redox reaction
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.

to release energy slowly in a step-by-step process.
A positive cell potential indicates that the redox reaction is spontaneous under standard conditions. This means that the reactants have a higher free energy than the products, leading to a favorable reaction that can occur without external energy input. Additionally, it suggests that the reduction half-reaction has a greater tendency to gain electrons compared to the oxidation half-reaction losing them.
A redox reaction can be identified by the transfer of electrons between reactants. Look for changes in oxidation states of elements involved in the reaction to determine if it is a redox reaction.
