Description

"Verfahren und Anordnung zur Heizung von elektrochemischen Brennstoffelementen11 Gegenstand der Efindung sind elektrochemische Brennstoffzellen. Mittels derartiger Elemente kann man die chemische Energie der Brennstoffe direkt in elektrische Energie umwandeln, ohne - wie bei dem Umweg Über Dampfkrafta-grogate oder Verbbennungsmotoren - die .#irkungsgradbegrenzung bei Umwandlung der Wärme in mechanische Arbeit entsprechend dem zgeiten.£4auptsatz der Thermodynamik in Kauf nehmen zu müssen. weitere Vo--teile solcher Elemente sind u.a. kleineE spezifisches Volumen, Fortfall bewegter Teile und laut#:gses Arbeiten, nben hoher.Überlastbarkeit."Process and arrangement for heating electrochemical fuel elements11 The subject matter of the invention are electrochemical fuel cells. By means of such elements the chemical energy of the fuel can be converted directly into electrical energy without - as with the detour via steam power generators or combustion engines - the efficiency limitation Conversion of heat into mechanical work in accordance with the timely law of thermodynamics. Further advantages of such elements include small specific volume, no moving parts and, according to #: all work, besides high overload capacity.

Elektrochemische Brennstoffelemente sind also galvanische Zellen, die mit festen flÜssigen, oder gasförmigen Brennstoffen betrieben werden und die freie Energie des Brennstoffes elektrochemisch ausnutzeii. Ihre wesentlichen Teile sind Anode und Kathode und der Elektrolyt. Es existieren zahlreiche är ten bzw. verschiedene Entwicklungsrichtungen solcher Brennstoffelemente, so etwa HochtemDeratur-und Niedertemperatur-Elemente. So sind z.B. solche Niedertemperaturelemente bekannt, die bei Temperaturen von 20 bis 80 0 C arbeiten.Electrochemical fuel elements are galvanic cells that are operated with solid liquid or gaseous fuels and electrochemically utilize the free energy of the fuel. Its essential parts are the anode and cathode and the electrolyte. There are numerous types or different directions of development of such fuel elements, such as high-temperature and low-temperature elements. For example, low-temperature elements which operate at temperatures of 20 to 80 ° C. are known.

Der für die einzelne Zellenart jeweils charakteristische Temperaturbereich oder Temperaturpegel muß unbedin,-t gehalten werden. Das gilt auch für die Zeit der Stillsetzung des Elementes, weil sonst eine iViederingangsetzung nicht gewährleistet ist. Die Sicherstellung der Temperaturhaltung bzw. entsprechender Heizung der Elemente in wirtschaftlicher und baulich günstiger 'leise-gehbrt zu den schwierigsten', bei praktischer VerNendung von Brennstoffzellen auftretenden Proble-. men.The characteristic temperature range for the individual cell type or temperature level must be kept absolutely. This also applies to time the shutdown of the element, because otherwise a restart cannot be guaranteed is. Ensuring that the temperature is maintained or that the elements are heated accordingly in economical and structurally favorable 'quietly belongs to the most difficult' practical use of fuel cells. men.

Durch das erfindungsgemäße Verfahren in seinen beschriebenen Varianten, wird eine relativ einfache und billige, dabei -.virkungsvolle Heizung, bzw. Temperaturhaltung fÜr die genannten Brennzellen geschaffen.With the method according to the invention in its described variants, will be a relatively simple and cheap, at the same time effective Heater, or created temperature maintenance for the fireplace insert mentioned.

Die Urfindung zeichnet sich aus durch Verwendung eines zusätzlichen Reizstromkreises in der Zelle, neben dem vorhandenen äußeren, die Funktion derselben bewirkenden Stromkreis, etwa eines zusätzlichen gesonderten Heizstromkreises, der durch entsprechend weitere Zuführung von Brennstoff soviel Energiezufuhr erhält, daß die Närmeverluste der Batterie nach außen gedeckt werden.The original invention is characterized by the use of an additional Stimulation circuit in the cell, in addition to the existing external, the function of the same causing circuit, such as an additional separate heating circuit, the receives as much energy from the corresponding additional supply of fuel, that the heat losses of the battery are covered to the outside.

Es kÖnnen auch separate Heizelektroden mit entsprechend großem inneren Niderstand innerhalb der Zellen angeordnet sein, xelche zur Erzeugung des Beizstromes kurzgeschlossen werden.There can also be separate heating electrodes with a correspondingly large inner Resistance can be arranged within the cells, xelche for generating the pickling current be short-circuited.

Eine Regelung der Heizung kann in vorteilhafter weiterer Ausgestaltting des Erfindungsged4nkens in den verschiedenen Fällen mittels Thermostatsteuerung erfolgen.A regulation of the heating can be advantageous in a further embodiment of the inventive concept in the various cases by means of thermostat control take place.
