WebYou get a reverse fuel cell (RFC) or regenerative fuel cell. If a fuel cell is a device that takes a chemical fuel and consumes it to produce electricity and a waste product, an RFC can be thought of as a device that takes that waste product and electricity to return the original chemical fuel. Indeed any fuel cell chemistry can be run in ... Webregenerative fuel cells, and commercial development of fuel cell technology will improve both the energy density and electrical efficiency of the RFCS. INTRODUCTION NASA has fl)r some time recognized the potential for a RFCS to store large amounts of energy for space applications where energy production is cyclic, as is the case for solar ...
A regenerative fuel cell or reverse fuel cell (RFC) is a fuel cell run in reverse mode, which consumes electricity and chemical B to produce chemical A. By definition, the process of any fuel cell could be reversed. However, a given device is usually optimized for operating in one mode and may not be built in such … See more A hydrogen fueled proton exchange membrane fuel cell, for example, uses hydrogen gas (H2) and oxygen (O2) to produce electricity and water (H2O); a regenerative hydrogen fuel cell uses electricity and water … See more • Glossary of fuel cell terms • Hydrogen technologies • Flow Battery See more One example of RFC is solid oxide regenerative fuel cell. Solid oxide fuel cell operates at high temperatures with high fuel-to-electricity conversion ratios and it is a good candidate for high temperature electrolysis.
