Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Bachelor Thesis from the year 2015 in the subject Engineering - Mechanical Engineering, grade: 1,7, Swiss Federal Institute of Technology Zurich (Institute of machine tools and manufacturing), language: English, abstract: With the rising cost of ener…gy, the increasing environmental awareness and the global warming, alternative drive systems are becoming increasingly important. Here, the fuel cell technology makes as clean and reliable method of energy production a great contribution.Many automotive companies like Hyundai, Daimler and Toyota are working intensively on fuel cell vehicles. Toyota has succeeded in December 2014 to bring the first car powered by hydrogen, the Toyota Mirai, on the market and it expects in the 2020s already with tens of thousands of vehicles annually.Therefore, the sales numbers will be increasing, which will require a mass production of fuel cells.Fuel cell technology is based on the principle of electrolysis. In order to generate electricity, hydrogen and oxygen are supplied to the fuel cell, where they react to electricity, water and heat. Thus cars powered by fuel cells have many advantages over cars with conventional sources, because they are environmentally friendly and save the long load time characterizing electric cars.However, the current manufacturing way does not meet the requirements of mass production. To date, the components of the fuel cell are often assembled to a stack without sufficient testing, which significantly increases the potential for errors. After assembly, an end-of-line test is performed, wherein the fuel cell and its functions are checked up for up to 24 hours. To achieve higher production volume, the duration of the end-of-line tests must be reduced to a few minutes. This requires a total quality management and quality assurance during production in order to achieve a quick and error-free one. The aim of this work is to shorten the duration of the end-of-line test by the development of a montage accompanying controlplan.The first part deals with the basics of the fuel cell technology. The most important historical events of the development of fuel cells are mentioned. In order to understand their functioning, the chemical and physical principles are explained and the functions of the individual components are described.In the second part, a Failure mode and effect analysis (FMEA) is performed. Based on a literature review, this analysis aims at determining the most important errors in the components of the fuel cell. Its results deduce the most necessary test characteristics to be checked during the manufacturing of the fuel cell. [.].

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Studienarbeit aus dem Jahr 2016 im Fachbereich BWL - Unternehmensforschung, Operations Research, Note: 2.0, Universität Stuttgart, Veranstaltung: Technologiemanagement, Sprache: Deutsch, Abstract: Mit steigender Nachfrage und wachsendem Konkurrenzdru…ck kennt die Elektromobilität seit den letzten Jahren einen steigenden Trend. Verschiedene Aspekte spielen dabei eine wichtige Rolle: politische Aspekte wie strengere Regulationen, Kaufprämien und Investitionen in die Ladeinfrastruktur, Ökologische Aspekte wie das hohe CO2-Reduktionspotential von Elektroautos, technologische Aspekte wie die Batterietechnologie, ökonomische Aspekte wie die Nachfrage nach Rohstoffen (Erdöl, Kupfer und Lithium) und gesellschaftliche Aspekte wie die Akzeptanz der Elektromobilität bei den Kunden.Eine steigende Produktion von Elektroautos wird einen Wandel in der Wertschöpfungs- und Beschäftigungsstruktur herbeiführen. Davon ist Baden-Württemberg als internationaler Player in der Automobilindustrie mit ca. 220.000 Beschäftigte und mehr als 113 Milliarden Euro Umsatz stark betroffen.Bei Elektrofahrzeugen entfallen mehrere Komponenten des Antriebsstrangs wie Verbrennungsmotor Getriebe und Kupplung. Bei Hybridfahrzeugen wird zusätzlich zum konventionellen Powertrain ein elektrischer Antriebsstrang verbaut. Dieser Wandel führt zu einer Verschiebung der Wertschöpfungsanteile und zu sinkenden Umsätzen bei den Zulieferern von konventionellen Komponenten und zu steigenden Umsätzen bei den Zulieferern von Elektrik/Elektronik- und Batteriekomponenten.Durch diesen Wandel steigt das Beschäftigungspotential in der Batterieindustrie auf 3622 bis 4132. Bei den Zulieferern von Leistungselektronik, Elektromotoren und Ladesysteme steigt ebenfalls das Potenzial auf 2750 bis 3137. Bei den konventionellen Komponenten sinkt das Potential um 970 bis 1106. Bei den Effizienztechnologien verringert es sich auch um 1098 bis 1253.Trotz dem hohen Beschäftigungspotential bei der Batterieindustrie wird es kurz- bis mittelfristig in Baden-Württemberg aus mangelnder Wirtschaftlichkeit, hohem Lohnniveau, nicht ausreichender Nachfrage, fehlenden Skaleneffekten und starkem Wettbewerb aus Asien und den USA für die aktuelle Generation der Batterietechnologie keine Batteriefabrik geben.
