Description
Die Erfindung betrifft ein Verfahren zur Nutzung der bei einer Hochtemperatur-Brennstoffzellenvorrichtung während eines Ladevorganges in einer Ladesäule für die E-Mobilität entstehenden Abwärme, umfassend die Schritte:
- - Erzeugung eines elektrischen Stroms für den Ladevorgang durch mindestens eine Hochtemperatur-Brennstoffzelle und Starten des Ladevorgangs an der Ladesäule,
- - Transport der Abwärme zu einer Kältemaschine,
- - Nutzung der mit der Abwärme produzierten Kühlleistung in einer Einrichtung mit Besucherverkehr.

Brennstoffzellen dienen dazu, in einer chemischen Reaktion zwischen einem wasserstoffhaltigen Brennstoff und einem sauerstoffhaltigen Oxidationsmittel, in der Regel Luft, elektrische Energie bereitzustellen. Bei einer Festoxid-Brennstoffzelle (Solid Oxide Fuel Cell SOFC) besteht dabei eine Elektrolytschicht aus einem namensgebenden festen Werkstoff, z.B. keramischen yttriumdotierten Zirkoniumdioxid, der in der Lage ist, Sauerstoffionen zu leiten, während Elektronen nicht geleitet werden. Die Elektrolytschicht ist zwischen zwei Elektrodenschichten aufgenommen, nämlich der Kathodenschicht, der die Luft zugeführt wird, und der Anodenschicht, die mit dem Brennstoff versorgt wird, der durch H2, CO, CH4 oder ähnliche Kohlenwasserstoffe gebildet sein kann. Wird die Luft durch die Kathodenschicht zu der Elektrolytschicht geführt, nimmt der Sauerstoff zwei Elektronen auf und die gebildeten Sauerstoffionen O2- bewegen sich durch die Elektrolytschicht zu der Anodenschicht, wobei die Sauerstoffionen dort mit dem Brennstoff reagieren unter Bildung von Wasser und CO2. Kathodenseitig findet die folgende Reaktion statt: ½ O2 + 2e- → 2O2- (Reduktion/Elektronenaufnahme). An der Anode erfolgen die folgende Reaktionen: H2 + O2- → H2O + 2 e- sowie CO + O2- → CO2 + 2e- (Oxidation/Elektronenabgabe).Fuel cells serve to provide electrical energy in a chemical reaction between a hydrogen-containing fuel and an oxygen-containing oxidizing agent, usually air. In a solid oxide fuel cell (SOFC), an electrolyte layer consists of a solid material that gives it its name, eg ceramic yttrium-doped zirconium dioxide, which is able to conduct oxygen ions while electrons are not conducted. The electrolyte layer is sandwiched between two electrode layers, namely the cathode layer, which is supplied with the air, and the anode layer, which is supplied with the fuel, which may be formed by H 2 , CO, CH 4 or similar hydrocarbons. If the air is conducted through the cathode layer to the electrolyte layer, the oxygen takes up two electrons and the oxygen ions O 2- formed move through the electrolyte layer to the anode layer, where the oxygen ions react with the fuel to form water and CO 2 . The following reaction takes place on the cathode side: ½ O 2 + 2e - → 2O 2- (reduction/electron acceptance). The following reactions take place at the anode: H 2 + O 2- → H 2 O + 2e - and CO + O 2- → CO 2 + 2e - (oxidation/donation of electrons).
Festoxid-Brennstoffzellen benötigen hohe Temperaturen über 700°C, bei denen sie betrieben werden.Solid oxide fuel cells require high temperatures in excess of 700°C at which to operate.
Bei der steigenden Anzahl an Brennstoffzellen-Fahrzeugen wird eine steigende Anzahl an Ladesäulen, an strategisch günstigen Punkten, wie zum Beispiel einem Supermarktparkplatz, benötigt. Allerdings sind die elektrischen Netze nicht für derartige Leistungen ausgelegt. Alternativ besteht die Möglichkeit, eine Hochtemperatur-Brennstoffzelle zu Erzeugung des elektrischen Stroms in den Ladesäulen anzuordnen, deren Brennstoff über ein Gasnetz, insbesondere für Erdgas, bereit gestellt werden kann, da die Kapazität des Gasnetzes für den Energietransport ausreicht. Diese Hochtemperatur-Brennstoffzelle produziert eine große Menge an Abwärme.With the increasing number of fuel cell vehicles, an increasing number of charging stations is required at strategically favorable points, such as a supermarket parking lot. However, the electrical networks are not designed for such power. Alternatively, there is the possibility of arranging a high-temperature fuel cell to generate the electricity in the charging stations, the fuel of which can be provided via a gas network, in particular for natural gas, since the capacity of the gas network is sufficient for transporting energy. This high-temperature fuel cell produces a large amount of waste heat.
In der
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bereit zu stellen, mit dem umweltfreundlich die Ladung batteriebetriebener Kraftfahrzeuge erfolgen kann.The object of the present invention is to provide a method with which battery-operated motor vehicles can be charged in an environmentally friendly manner.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by a method having the features of claim 1. Advantageous configurations with expedient developments of the invention are specified in the dependent claims.
Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, dass es nicht einen Verbrennungsmotor als konventionellen Generator zur Stromerzeugung nutzt. Vielmehr wird eine Hochtemperatur-Brennstoffzelle verwendet, wobei die Abwärme der Hochtemperatur-Brennstoffzellenvorrichtung nicht an die Umgebung abgegeben wird, sondern die Abwärme zur Kälteerzeugung in einer Einrichtung mit Besucherverkehr genutzt wird. Die erzeugte Kälte kann beispielweise für die Temperierung von Kühltheken und Gefriertruhen in einem Supermarkt verwendet werden. Dort liegt ein großer Besucherverkehr mit vielen Besuchern vor, die auch eine kurze Verweildauer haben. Dadurch steigt die Nachfrage nach Ladestrom und die Hochtemperatur-Brennstoffzelle kann optimal kontinuierlich betrieben werden.The method according to the invention is characterized in that it does not use an internal combustion engine as a conventional generator to generate electricity. Rather, a high-temperature fuel cell is used, with the waste heat from the high-temperature fuel cell device not being released into the environment, but rather the waste heat being used to generate cold in a facility with visitor traffic. The cold generated can be used, for example, to control the temperature of refrigerated counters and freezers in a supermarket. There is a lot of visitor traffic with many visitors who also have a short stay. This increases the demand for charging current and the high-temperature fuel cell can be optimally operated continuously.
Weiterhin ist es vorteilhaft, wenn mindestens eine Festoxid-Brennstoffzelle in der Brennstoffzellenvorrichtung den elektrischen Strom erzeugt.Furthermore, it is advantageous if at least one solid oxide fuel cell generates the electric current in the fuel cell device.
Vorteilhaft ist es weiterhin, dass die Hochtemperatur-Brennstoffzelle den elektrischen Strom für eine Mehrzahl an Ladesäulen erzeugt, da die Wartung einer zentralen Hochtemperatur-Brennstoffzellenvorrichtung wirtschaftlicher ist, als die Wartung von vielen über die Einrichtung verteilten Hochtemperatur-Brennstoffzellenvorrichtungen.It is also advantageous that the high-temperature fuel cell generates the electricity for a plurality of charging stations, since the maintenance of a central high-temperature fuel cell device is more economical than the maintenance of many high-temperature fuel cell devices distributed over the facility.
Weiterhin ist es vorteilhaft, dass die Kühlleistung in der Ladesäule erzeugt und mittels eines Transportmediums aus Luft oder einem Wasserglykolgemisch zur Einrichtung transportiert wird.Furthermore, it is advantageous that the cooling capacity is generated in the charging station and transported to the facility by means of a transport medium made of air or a water-glycol mixture.
Es ist weiterhin sinnvoll, wenn in einem Speicher das gekühlte Transportmedium gespeichert wird. Die Kälteleistung, die zu Zeiten starker Ladesäulenauslastung generiert wird, kann so für Zeiten mit geringerer Ladesäulenauslastung gespeichert werden, wodurch eine gleichmäßige Kühlleistung erreicht wird.It is also useful if the cooled transport medium is stored in a store. The cooling capacity that is generated at times of high charging station utilization can thus be stored for times of lower charging station utilization, which means that an even cooling capacity is achieved.
Es ist weiterhin vorteilhaft, dass die Kühlleistung durch eine Absorptionskälteanlage bereitgestellt wird. Absorptionskälteanlagen sind durch nur wenige bewegliche Bauteile wenig störanfällig und damit wartungsarm und kostengünstig im Unterhalt. Weiterhin zeichnen sie sich durch lange Stand- und Nutzzeiten aus und weisen eine gute Abwärmenutzung auf.It is also advantageous that the cooling capacity is provided by an absorption chiller. Absorption chillers are less prone to failure due to only a few moving components and are therefore low-maintenance and inexpensive to run. Furthermore, they are characterized by a long service life and use and have a good use of waste heat.
Alternativ besteht die Möglichkeit, dass die Kühlleistung durch einen Thermokompressor mit einer Strahlpumpe bereitgestellt wird. Thermokompressoren zeichnen sich durch eine lange Lebensdauer, eine einfache Bauweise und geringen Investitionskosten aus.Alternatively, there is the possibility that the cooling capacity is provided by a thermal compressor with a jet pump. Thermocompressors are characterized by a long service life, a simple design and low investment costs.
Sinnvoll ist es weiterhin, wenn das Kühlleistungsniveau über mindestens einen Kältekreislauf mit zwei Verdampfern auf eine Temperatur oberhalb des Gefrierpunktes und eine Temperatur unterhalb des Gefrierpunktes eingestellt wird, wodurch ein großes Einsatzgebiet des Verfahrens ermöglicht wird, nämlich sowohl für Gefriergut bei tiefen Temperaturen als auch für lediglich Kühlbedürftige Waren wie Milch.It is also useful if the cooling capacity level is set to a temperature above freezing point and a temperature below freezing point via at least one refrigeration circuit with two evaporators, which allows the method to be used in a wide range of applications, namely both for frozen goods at low temperatures and for frozen goods Goods that require refrigeration, such as milk.
Es ist weiterhin vorteilhaft, wenn die Kühlleistung zur Kühlung eines Supermarktes und/oder einer Eislaufanlage und/oder eines Hochhauses eingesetzt wird, da so die für eine Kühlung anfallenden Kosten gesenkt werden können und dort der gewünschte große Besucherverkehr vorliegt.It is also advantageous if the cooling power is used to cool a supermarket and/or an ice skating facility and/or a high-rise building, since the costs incurred for cooling can be reduced and the desired high level of visitor traffic is present there.
