Can regenerative fuel cells provide energy storage?
Electrochemical systems, including flow batteries and regenerative fuel cells, offer promising solutions to this challenge, possessing the capability to provide large-scale, long-duration energy storage, thereby complementing the rapid response of batteries and the high energy density of fuels [5, 6].
What is a fuel cell electrolyte?
Electrodes are in a liquid or solid electrolyte through which ions can flow. The electrodes are often coated in a catalyst, such as platinum, to speed up chemical reactions . A fuel cell contains a separator, typically called a membrane, which selectively allows ions to flow.
How does a fuel cell work?
A fuel cell contains a separator, typically called a membrane, which selectively allows ions to flow. As with the separator of a battery, it is typically made from a thin polymer. Fuel is added at the anode, and an oxidizer is added at the cathode. Typically, both the fuel and oxidizer are liquids or gases.
What is a flow battery?
Flow batteries generally have high round-trip efficiency (typically 70–85 %) and long cycle life (up to 20,000 cycles or more), making them a reliable energy storage technology . The electrodes in a flow battery play a crucial role in the electrochemical reactions that occur during the charging and discharging process .
