This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research work was to put into evidence the electrocatalytic activity of various molecular compounds with regard to the electrochemical reduction of carbon dioxide, at low temperature, in view of potential application in PEM cells. First, reference values have been measured on copper and nickel metals. Then the performances of some molecular compounds have been measured. The electrochemical activity of these different compounds has been put into evidence by recording the current-potential relationships in various media. The role of a hydrogen source for the reduction processes has been evaluated. The formation of reduction products has been put into evidence and analyzed by gas phase chromatography. Then, a PEM cell has been developed and preliminary tests have been performed. PEM cells with either an oxygen-evolving anode or a hydrogen-consuming anode have been tested. Using nickel molecular complexes, it has been possible to lower the potential of the cathode and to reduce CO2 but the parasite hydrogen evolution reaction was found to remain predominant.

Download or read book Gaseous Carbon Waste Streams Utilization written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

Download or read book Polymer Electrolyte Fuel Cell Durability written by Felix N. Büchi and published by Springer Science & Business Media. This book was released on 2009-02-08 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers a significant number of R&D projects, performed mostly after 2000, devoted to the understanding and prevention of performance degradation processes in polymer electrolyte fuel cells (PEFCs). The extent and severity of performance degradation processes in PEFCs were recognized rather gradually. Indeed, the recognition overlapped with a significant number of industrial dem- strations of fuel cell powered vehicles, which would suggest a degree of technology maturity beyond the resaolution of fundamental failure mechanisms. An intriguing question, therefore, is why has there been this apparent delay in addressing fun- mental performance stability requirements. The apparent answer is that testing of the power system under fully realistic operation conditions was one prerequisite for revealing the nature and extent of some key modes of PEFC stack failure. Such modes of failure were not exposed to a similar degree, or not at all, in earlier tests of PEFC stacks which were not performed under fully relevant conditions, parti- larly such tests which did not include multiple on–off and/or high power–low power cycles typical for transportation and mobile power applications of PEFCs. Long-term testing of PEFCs reported in the early 1990s by both Los Alamos National Laboratory and Ballard Power was performed under conditions of c- stant cell voltage, typically near the maximum power point of the PEFC.
Download or read book Low Temperature Electrocatalytic Reduction of Carbon Dioxide Utilizing Room Temperature Ionic Liquids written by Brian A. Rosen and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial photosynthesis, where one uses electricity from solar, or wind, to convert water and carbon dioxide into a hydrocarbon fuel could provide a viable route to renewable fuels but so far the results have been stymied because of the lack of a CO2 conversion catalyst that operates at low overpotentials. In this study we report a catalyst system that shows CO2 conversion at low overpotentials. The system uses two different catalysts to achieve the conversion. First an ionic liquid or ionic salt is used to catalyze the formation of a (CO2)0̐Ư intermediate. Then a transition metal is used to catalyze the conversion of the (CO2)0̐Ư intermediate into useful products. CO formation is first observed at -250mV with respect to a standard hydrogen electrode compared to 800mV in the absence of the ionic liquid. Thus, CO2 conversion to CO can occur without the large energy loss associated with a high overpotential raising the possibility of practical artificial photosynthesis. The reduction of CO2 in 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF4) was studied in an H-type electrochemical cell, an in-situ SFG/SERS cell, and a continuous flow CO2 electrolysis cell. Results from these experiments suggest that the EMIM BF4 is able to catalyze the reaction in such a way that opens the door for the practical low potential and temperature conversion of CO2.
