Description
Die Erfindung betrifft ein Brennstoffzellensystem mit wenigstens einer Brennstoffzelle und mit einer Gaserzeugungseinrichtung.The invention relates to a fuel cell system with at least one fuel cell and with a gas generating device.
Gattungsgemäße Brennstoffzellensysteme sind
aus dem allgemeinen Stand der Technik bekannt. Nur beispielhaft
wird hierzu auf die
In der den Brennstoffzellen vorgeschalteten Gaserzeugungseinrichtung wird der für das Brennstoffzellensystem notwendige Wasserstoff aus Kohlenwasserstoffen, wie z.B. Erdgas, Propan, Butan, Benzin, Diesel oder Kerosin, gewonnen. Für diesen Prozess ist innerhalb des Gaserzeugungssystems eine Betriebstemperatur von mehr als 500 bis 600 °C erforderlich. In den Brennstoffzellen selbst herrscht eine Betriebstemperatur von ca. 80 °C.In the fuel cell upstream gas generating device will the for the fuel cell system necessary hydrogen from hydrocarbons, such as. Natural gas, propane, butane, gasoline, diesel or kerosene, won. For this process is within the gas generating system an operating temperature of more than 500 to 600 ° C required. In the fuel cell itself, there is an operating temperature of about 80 ° C.
Beim Kaltstart des Systems ist es in der Rufheizphase erforderlich, die oben angegebenen Betriebstemperaturen zu erreichen, was mehrere Minuten in Anspruch nehmen kann.When cold starting the system it is required in the call heating phase, the above-mentioned operating temperatures reach, which can take several minutes.
Da es in der beschriebenen Aufwärm- bzw. Rufheizphase nicht möglich ist, der Brennstoffzelle Strom zu entnehmen, stellt jeder Kaltstart des Brennstoffzellensystems einen unnötigen Energieverbrauch dar, was insbesondere dann stark zum Tragen kommt, wenn solche Aufwärmphasen während der Betriebszeit des Brennstoffzellensystems häufig auftreten oder wenn die Aufwärmphasen im Vergleich zu dem späteren Betrieb des Brennstoffzellensystems sehr lang sind.Since it is in the described warming or Rufheizphase not possible is to take the fuel cell power, every cold start the fuel cell system is an unnecessary energy consumption, which is particularly strong when such warm-up phases during the Operating time of the fuel cell system often occur or if the warm-up phase compared to the later one Operation of the fuel cell system are very long.
Wenn beispielsweise während eines Betriebszyklus für einen kurzen Zeitraum keine elektrische Leistung benötigt wird, so muss das gesamte System bei kleiner Leistung betrieben werden, um eine nachfolgende Inbetriebnahme ohne zeitlichen Verzug zu gewährleisten. In diesem Zusammenhang ist allerdings nachteilig, dass der Wirkungsgrad von Brennstoffzellensystemen bei sinkender Last stark nachlässt.For example, during a Operating cycle for a short period no electrical power is needed so the whole system has to be run at low power, to ensure subsequent commissioning without any time delay. In this context, however, is disadvantageous that the efficiency of fuel cell systems decreases sharply with decreasing load.
Zum Erreichen der Betriebstemperatur werden im allgemeinen Stand der Technik häufig Startbrenner oder elektrische Heizeinrichtungen verwendet, die die oben genannten Nachteile allerdings nicht beseitigen können.To reach the operating temperature In the general state of the art, starters or electric motors are often used However, heaters used that do not have the disadvantages mentioned above can eliminate.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Brennstoffzellensystem mit einer Gaserzeugungseinrichtung zu schaffen, mit welchem die Aufwärmzeit bis zur möglichen Stromentnahme aus dem Brennstoffzellensystem drastisch verringert werden kann.It is therefore the task of the present Invention, a fuel cell system with a gas generating device to create, with which the warm-up time up to the possible Current consumption from the fuel cell system can be drastically reduced can.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this object is achieved by the solved in claim 1 features.
Durch die erfindungsgemäße Kombination einer thermischen Isolierung mit einer Heizeinrichtung für die Gaserzeugungseinrichtung können die für den Betrieb des Brennstoffzellensystems wesentlichen thermischen Massen stets auf Betriebstemperatur gehalten werden, so dass ein Standby-Betrieb des Brennstoffzellensystems möglich gemacht wird. Neben der Temperatur wird auf diese Weise auch der Druck der Gaserzeugungseinrichtung auf einem hohen Niveau gehalten, so dass die Startzeit wesentlich reduziert wird und ein schneller Start sowie ein kurzfristiges Abschalten des Brennstoffzellensystems möglich ist.The inventive combination of a thermal insulation with a heater for the gas generating device can the for the operation of the fuel cell system essential thermal Masses are always kept at operating temperature, so that a Standby operation of the fuel cell system is made possible. In addition to the Temperature is in this way also the pressure of the gas generating device kept at a high level, so the start time is significantly reduced and a quick start as well as a short-term shutdown the fuel cell system possible is.
In denjenigen Zeiten, in denen von der Brennstoffzelle keine elektrische Leistung angefordert wird, kann das Brennstoffzellensystem somit abgeschaltet bzw. in den Standby-Betrieb geschaltet werden, was zu einer erheblichen Kraftstoff- bzw. Energieersparnis führt.In those times in which of the fuel cell is not required to provide electrical power, Thus, the fuel cell system can be switched off or in standby mode be switched, resulting in a significant fuel and energy savings leads.
Das erfindungsgemäße Brennstoffzellensystem ist insbesondere für den Einsatz in z.B. Antriebssystemen für Mehrzweckloks oder Bordstromversorgung von NFZ und PKW sehr gut geeignet, da gerade in diesen Anwendungsfällen häufige Standby-Betriebszustände gefordert werden.The fuel cell system according to the invention is especially for use in e.g. Drive systems for multi-purpose locos or on-board power supply Of commercial vehicles and cars very well suited because especially in these applications, frequent standby operating conditions required become.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus den nachfolgend anhand der Zeichnung beispielhaft dargestellten Ausführungsbeispielen.Advantageous embodiments and Further developments of the invention will become apparent from the dependent claims and from those exemplified below with reference to the drawing Embodiments.
