This book was released on 2021-10-25 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical Power Sources: Fundamentals, Systems, and Applications: Hydrogen Production by Water Electrolysis offers a comprehensive overview about different hydrogen production technologies, including their technical features, development stage, recent advances, and technical and economic issues of system integration. Allied processes such as regenerative fuel cells and sea water electrolysis are also covered. For many years hydrogen production by water electrolysis was of minor importance, but research and development in the field has increased significantly in recent years, and a comprehensive overview is missing. This book bridges this gap and provides a general reference to the topic.Hydrogen production by water electrolysis is the main technology to integrate high shares of electricity from renewable energy sources and balance out the supply and demand match in the energy system. Different electrochemical approaches exist to produce hydrogen from RES (Renewable Energy Sources). - Covers the fundamentals of hydrogen production by water electrolysis - Reviews all relevant technologies comprehensively - Outlines important technical and economic issues of system integration - Includes commercial examples and demonstrates electrolyzer projects

Available in PDF, EPUB and Kindle. Book excerpt: A regenerative stack consisting of four hydrogen-oxygen fuel cells and two electrolysis cells was designed, fabricated, and successfully tested for 48 cycles. The regenerative stack was operated over the following range of parameters: fuel cell current densities from 50 amps/sq ft to 300 amps/sq ft, and temperatures current densities from 5 amps/sq ft to 90 amps/sq ft, and temperatures from 70F to 200F. Proper moisture transfer between fuel cells and electrolysis cells with vapor pressure gradients as the driving force was demonstrated at all operating conditions. The integrated stack fabricated and tested under this contract consists of a planar stack of four hydrogen/oxygen, alkaline electrolyte (KOH), low temperature, matrix fuel cells each about 2 inches by 10 inches and a planar stack of two 4.5 inch X 10 inch electrolysis cells of similar type. Water storage matrices are located adjacent to the hydrogen electrodes of both stacks and are separated by a hydrogen plenum. (Author).

This book was released on 2018-06-24 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. During charge cycle the RFC has absorbed input electrical power simulating a solar day cycle ranging from zero to 15 kWe peak, and delivered steady 5 kWe output power for periods exceeding 8 hr. Orderly transitions from charge to discharge mode, and return to charging after full discharge, have been accomplished without incident. Continuing test operations focus on: (1) Increasing the number of contiguous uninterrupted charge discharge cycles; (2) Increasing the performance envelope boundaries; (3) Operating the RFC as an energy storage device on a regular basis; (4) Gaining operational experience leading to development of fully automated operation; and (5) Developing instrumentation and in situ fluid sampling strategies to monitor health and anticipate breakdowns.

This book was released on 2018-07-08 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental test program was conducted to investigate the performance characteristics of an integrated regenerative fuel cell (IRFC) concept. The IRFC consists of a separate fuel cell unit and electrolysis cell unit in the same structure, with internal storage of fuel cell product water and external storage of electrolysis cell produced hydrogen and oxygen. The fuel cell unit incorporates an enhanced Orbiter-type cell capable of improved performance at reduced weight. The electrolysis cell features a NiCo2O4 catalyst oxygen evolution eletrode with a porous Teflon cover to retard electrolyte loss. Six complete IRFC assemblies were assembled and performance tested at an operating temperature of 200 F (93.3 C) and reactant pressures up to 170 psia (117.2 n/cu cm) on IRFC No. 4. Anomalous pressure charge/discharge characteristics were encountered during performance evaluation. A reversible fuel cell incorporating a proprietary bi-functional oxygen electrode operated satisfactory at 200 F (93.3 C) at reactant pressures up to 50 psia (41.4 n/cu cm) as a regenerative fuel cell for one cycle, before developing an electrical short in the fuel cell mode. Electrolysis cell 300-hour endurance tests demonstrated the electrolyte retention capability of the electrode Teflon cover and the performance stability of the bi-functional oxygen electrode at high potential.
