What is a cell with positive $E ° cell$ ?

Solution

Understanding the concept:
A cell is the source of energy that generates electric current through chemical reactions.
Explanation of positive $E ° cell$ :
The reaction will move forward if E $°$ (the redox reaction) is positive (spontaneous).
It is possible to generate electricity by a spontaneous process.
One type of electrochemical cell, the galvanic cell (also known as the voltaic cell), transforms the chemical energy of oxidants & reductants into electrical energy.
Electricity can only be created if a redox reaction is spontaneous
For a typical standard galvanic cell (voltaic cell), $E °$ is positive, meaning that $E °$ (cell) > 0
$E °$ (cell), also known as the standard potential difference of a cell or electromotive force (emf), is the highest voltage that a redox cell is capable of producing.
