{'electrochemical cell': [0, 0, 0, 1], 'electrolytic cell': [0, 0, 0, 1], 'primary cell': [0, 0, 0, 1], 'fuel cell': [0, 0, 0, 3], 'storage cell': [0, 0, 0, 1]}

The correct answer is option 3, which is a primary cell. A primary cell is an electrochemical cell that cannot be charged.

Let`s look at the other options to understand why they are not the correct answer:

- Option 1: An electrolytic cell is a type of cell that uses an electric current to drive a non-spontaneous chemical reaction. It can be charged and used for electrolysis.

- Option 2: A storage cell, also known as a rechargeable cell or secondary cell, is designed to be charged and discharged multiple times. It can store and release electrical energy.

- Option 4: A fuel cell is an electrochemical cell that converts the chemical energy of a fuel, such as hydrogen or methane, into electrical energy. Fuel cells can be recharged and used repeatedly.

Therefore, option 3 - primary cell - is the correct answer as it is the only type of electrochemical cell that cannot be charged.
