Sažetak
A regenerative fuel cell (RFC) is a device that can operate alternately as an electrolyzer and as a fuel cell. The electrolyzer and fuel cell functions can be integrated into a single stack of cells (unitized) or two separate (discrete) stacks may be used. Although RFC systems with different fuel/oxidizer combinations and electrolytes are possible, this paper will focus on hydrogen/oxygen systems using PEM electrolyte. In electrolysis mode the stack generates hydrogen (and oxygen) from electricity, and in fuel cell mode it generates electricity from stored hydrogen and oxygen or air. It is therefore an energy storage device (similar to a rechargeable battery) with hydrogen as a storage medium. The regenerative fuel cell has the highest achievable specific energy (>400 Wh/kg) of all rechargeable energy storage options. As such it may be used in applications where relatively large amounts of electricity need to be stored, such as energy storage for remote off-grid power sources, emergency or back-up power generation, zero emission vehicles, hybrid energy storage/propulsion systems for spacecraft, and high altitude long endurance solar rechargeable aircraft.
