claimFuel cells are electrochemical systems that convert the chemical energy of a fuel, such as hydrogen, and an oxidizing agent, such as oxygen, into electricity through a pair of redox reactions.
measurementFuel cells achieve over 99.99% system reliability and can be considered renewable depending on the source of the hydrogen and oxygen used.
claimStrategies to reduce electricity-related pollution and losses include reducing fossil fuel usage, increasing the adoption of renewable energy sources like photovoltaics and wind, utilizing fuel cells, integrating battery storage systems, and adopting plug-in electric vehicles.
claimUnlike batteries, fuel cells continuously require a supply of fuel and oxygen to sustain the power generation process, whereas batteries derive chemical energy from metals and their ions or oxides already contained within the device (with the exception of flow batteries).
claimHydrogen is expected to play a leading role in the development of fuel cells and as a fuel source to replace fossil fuels.
claimFuel cells and energy storage systems facilitate the use of variable renewable energy sources like wind, solar, and hydro by absorbing and storing energy for use during peak demand or when supply diminishes.
claimFuel cells are more efficient than combustion systems and can increase overall efficiency through cogeneration by utilizing the heat generated during power production for thermal applications.
claimElectricity is defined in the study as a secondary form of energy derived from primary sources such as wind, solar, hydro, nuclear, coal, and gas through indirect conversion (generators) or direct conversion (fuel cells and solar photovoltaics).
