They use the wrong kind of energy and they use too much of it. That's why other batteries are way better. One, they hardly use 6% as much as chemical fuel cells. Two, the chemical fuel cells pollute the air too.
Both fuel cells and primary cells are devices that convert chemical energy into electrical energy. The main difference is that primary cells use stored chemical energy in the form of a non-rechargeable chemical reaction, while fuel cells continuously receive fuel and an oxidizing agent to generate electricity through a controlled chemical reaction.
fuel cells converts chemical energy to eletrical power and the only waste product for fuel cells is water
Carbon and hydrogen
converts the chemical energy of a fuel and an oxzidizing into electricity.
ATP
Yes , energy can be stored as chemical energy, for example in batteries and fuel cells.

Filling fuel cells with lead shot would not be practical as the purpose of fuel cells is to convert chemical energy directly into electrical energy. Lead shot would not provide a suitable chemical reaction to generate electricity efficiently. Additionally, lead is a toxic material and using it in fuel cells could raise environmental and health concerns.
Two types of electromagnetic cells are photovoltaic cells, which convert sunlight into electricity, and fuel cells, which produce electricity through chemical reactions between fuel and oxygen.
Fuel cells differ from conventional batteries in their energy storage and conversion mechanisms. While batteries store energy in chemical form within the cell, fuel cells generate electricity through a chemical reaction between a fuel source and an oxidizing agent. This allows fuel cells to continuously produce electricity as long as fuel is supplied, unlike batteries which have a limited capacity and need to be recharged.
More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX
The waste byproducts of hydrogen fuel cells are heat and water vapor. When hydrogen is converted into electricity in a fuel cell through a chemical reaction with oxygen, these are the only emissions produced, making fuel cells a clean and efficient energy source.
