    Construction of the closed loop system began in at the NASA Glenn Research Center in Cleveland, Ohio. System checkout was completed, and testing began, in July of The initial test sequences were done with only a fuel cell or electrolyzer in the test rig. Those tests were used to verify the test apparatus, procedures, and software. The closed-cycle hydrogen-oxygen PEM regenerative fuel cell (RFC) at the NASA Glenn Research Center has successfully demonstrated closed cycle operation at rated power for multiple charge-discharge cycles.

      Figure 6: A fuel cell lab test station for a fuel cell stack. In order to begin testing the fuel cell correctly, the test setup needs to be verified, the cell conditioned, and baseline testing conditions and operating parameters must be established. Regenerative fuel cell systems provide energy storage at a scale that is larger than what is practical with advanced batteries.

    For the most part while the chemistries are similar fuel cells are not batteries because they require a chemical fuel, you would have to pair a fuel cell with an electrolyser to get the same effect. However there is a type of fuel cell designed to run both forwards and backwards, the unitized regenerative fuel cell . Giner has unique experience in the design and provision of regenerative fuel cells for this application. Regenerative Fuel Cells combine an electrolyzer that converts solar energy into stored chemical energy (pressurized hydrogen (H 2) and oxygen (O 2) gas), with a fuel cell that can convert the chemical energy back to electric power and water.

Fuel Cell Testing Laboratory Facility Overview. The Fuel Cell Testing Laboratory is located in Building and consists of multiple testing cell has been designed to accommodate a wide variety of sizes and types of fuel cells, including hydrogen/air and hydrogen/oxygen fuel cells ranging from 1 kW up to kW.

Introduction: operational principles and types of regenerative fuel cell. A regenerative fuel cell (RFC) is a single device or system capable of functioning either as an electrolyser or a fuel cell (Frank, ).The reversible reaction most commonly used in an RFC is the splitting of water into its constituent elements, hydrogen and oxygen, and their recombination to form water once again.

– Unitized Regenerative Fuel Cell: •Could save volume/weight of extra stack, however, water management becomes difficult. – Fuel Cell Mode: •Almost impossible to avoid liquid water flooding the cathode in pressurized systems operating at low stoich.

•Systems must operate at lower pressure/high recirculation rates to remove water. Books. AIAA Education Series; Library of Flight; Test of Hydrogen-Oxygen PEM Fuel Cell Stack at NASA Glenn Research Center.

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, one as a fuel cell and one as an electrolyzer.

NASA Glenn Research Center (GRC) has recently demonstrated a polymer electrolyte membrane (PEM) based regenerative fuel cell system (RFCS) that operated for five contiguous back-to-back 24 h charge/discharge cycles over a period of h ⁠.The system operated continuously at full rated power with no significant reactant loss, breakdowns, or degradations from June 26 through July 1, Subtopic: closed cycle hydrogen-oxygen PEM regenerative fuel cell The closed-cycle hydrogen-oxygen PEM regenerative fuel cell (RFC) at NASA Glenn Research Center has demonstrated multiple back to back contiguous cycles at rated power, and round trip efficiencies up to 52 percent.

It is the first fully closed cycle regenerative fuel cell ever demonstrated (entire system is.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 a way that it can be operated backwards.
