Book Description :

The focus of this book is on electrochemical hydrogen technologies and fuel cell technologies in particular. Precipitated by the energy crisis in 1973, intensive work has been done world-wide on hydrogen technologies. Water electrolysis was the main objective. The steady increase of combustion of fossil fuels, with the ensuing CO 2 content in the environment, has led to a greater need to change the use of energy conversion and consumption. Hydrogen, based on nuclear and renewable energies, could become indispensable for energy storage and long range transport. Only electrolysis allows the conversion of electrical energy into hydrogen with high efficiency. Prior to the introduction of non-polluting but very expensive methods for energy harvesting and conversion, it is first necessary to ascertain how to save energy and to refurbish energy conversion systems to obtain the highest efficiencies with the lowest CO 2 emissions, e.g. in large scale electricity generation.Collected here in 7 chapters are the contributions of internationally known electrochemical engineers who work actively in this rapidly developing field. The relevant work reviewed extends from fundamental findings in the field of technical electrocatalysis of hydrogen and oxygen reactions to water electrolysis, chlor-alkali electrolysis (which is still practically the most important process for electrolytic hydrogen generation), thermochemical hybrid cycles and on finally to fuel cells. The latter in their advanced form of heavy, high-temperature cells promise to become the basis for highly efficient electric power plants for converting the chemical energy of fossil fuels, or hydrogen from fossil combustibles like methane, or coal into electricity with system efficiencies greater than 55%.The material presented in this volume should prove of immense value to electrochemical engineers, producers of electrolyzers and fuel cells, electrical engineers and political/technical decision makers. It will also be of use to academic teachers lecturing on electrochemistry and advanced technologies.

Covering the various aspects of this fast-evolving field, this comprehensive book includes the fundamentals and a comparison of current applications, while focusing on the latest, novel achievements and future directions. The introductory chapters explore the thermodynamic and electrochemical processes to better understand how electrolysis cells work, and how these can be combined to build large electrolysis modules. The book then goes on to discuss the electrolysis process and the characteristics, advantages, drawbacks, and challenges of the main existing electrolysis technologies. Current manufacturers and the main features of commercially available electrolyzers are extensively reviewed. The final chapters then present the possible configurations for integrating water electrolysis units with renewable energy sources in both autonomous and grid-connected systems, and comment on some relevant demonstration projects. Written by an internationally renowned team from academia and industry, the result is an invaluable review of the field and a discussion of known limitations and future perspectives.

Book Description :

Polymer electrolyte membrane fuel cells(PEMFCs) are energy conversion devices with significant potential. The factors preventing them from becoming widespread concern production and distribution of hydrogen. Developing an efficient hydrogen infrastructure with an approachable rollout plan is an essential step towards the future of fuel cells. Water electrolysis is limited by the thermodynamics of the process, which leads to high electrical consumption and significant materials challenges. Alternative methods for cleanly generating hydrogen while using a lower cell voltage are required. PEM based electrolyzers can operate with a "depolarized anode", whereby they become significantly less power hungry. This thesis explores two techniques for chemically depolarized electrolyzer anodes. These include a methanol anode and a phosphomolybdic acid anode. To improve the phosphomolybdic acid anode we have characterized the basic electrochemical behavior of phosphomolybdic acid, the anode behavior in a zerogap electrochemical cell, and the biomass oxidation characteristics of several Keggin ions and potential oxidation promoters. The methanol cathode was evaluated using a dynamic hydrogen electrode and shown to be significantly more sensitive to crossover induced voltage losses than was previously reported. Phosphomolybdic acid oxidation kinetics were examined and found to be facile, despite a change in mechanism which occurs after bulk reduction. The temperature dependent diffusion coefficient was found to be on the same order as other likely small, redox active molecules. A previously unreported crossover phenomena was noted and the diffusion coefficient through NAFION was calculated as on the same order as vanadium. The whole cell performance of the phosphomolybdic acid mediated electrolyzer was examined and found to be highly dependent on supporting electrolyte, temperature, and electrode materials. The optimized condition of 5 M HCl and 80 Celsius showed significant improvement in exchange current density, versus the standard conditions of room temperature and no supporting acid, used in the literature. The electrode kinetics have now been removed as a major problem in the system design. While the electrochemical performance of the POM mediated electrolyzer was sufficient, the glycerol oxidation rates were found to be lacking. Vanadium, iron, and hydrochloric acid were the most effective additives; while sulfuric acid decreased reaction rates.
