In 2008, professor Jeremy P. Meyers, in the Electrochemical Society journal Interface wrote that fuel cells "are not as efficient as batteries, due primarily to the inefficiency of the oxygen reduction reaction. [T]hey make the most sense for operation disconnected from the grid, or when fuel can be provided continuously. For applications that require frequent and relatively rapid start-ups where zero emissions are a requirement, as in enclosed spaces such as warehouses." Also i
