Which of the following technologies is primarily focused on generating energy?

Fuel cell technology is focused on generating energy by converting chemical energy, usually from hydrogen and oxygen, directly into electricity through an electrochemical reaction. This process is highly efficient and produces only water and heat as byproducts, making it an environmentally friendly option for power generation.

While solar panel, wind turbine, and geothermal energy technologies also generate energy, they do so through different mechanisms—solar panels convert sunlight into electricity, wind turbines harness wind energy, and geothermal technology utilizes heat from the Earth's interior. Each of these technologies plays a crucial role in the renewable energy landscape, but fuel cell technology is specifically defined by its method of transforming chemical energy into electrical energy.
