Description

  • Die vorliegende Erfindung betrifft eine Elektrolyseapparatur, insbesondere eine Elektrolyseapparatur für ein Fahrzeug.
  • Die US 5,332,630 offenbart ein Fahrzeug eigenes Wiederaufladesystem für batteriebetriebene elektrische Fahrzeuge, welches, unter anderem, ein Brennstoffzellenmagazin und ein Kühlsystem einschließt. Das Kühlsystem kann entweder die Form eines Kühlmantels annehmen, der eine Brennstoffzellenkammer definiert, die das Brennstoffzellenmagazin umgibt, oder, alternativ, eine Kühlanordnung, die eine Reihe von Kühlelementen umfaßt, die zwischen Brennstoffzellenmagazinen angeordnet sind und mechanisch von dem Brennstoffzellenmagazin isoliert sind. Im Falle, wo ein Kühlmantel verwendet wird, umfaßt die Anordnung ebenfalls einen thermischen Steuerzylinder, der zwischen einer eingesetzten Position, in welcher er axial mit dem Brennstoffmagazin ausgerichtet ist, und einer verdrückten Position, in welcher er axial von dem Brennstoffzellenmagazin abgesetzt ist, beweglich ist. Der thermische Steuerzylinder stellt somit ein Mittel für einen variablen thermischen Widerstand zwischen dem Brennstoffzellenmagazin und dem Kühlmantel bereit. Im Falle, wo eine Kühlanordnung verwendet wird, umfaßt die Anordnung eine Vielzahl von Kühlelementen, durch welche ein Kühlmittel zirkuliert wird. In jeder Ausführungsform wird eine Wärmegewinnung hauptsächlich mittels thermischer Strahlung erreicht.
  • Die JP 07-122280 offenbart ein Magazin, das eine Einheitsbrennstoffzelle integriert. Drei Fließwege für Kühlmittel laufen durch das Magazin, wobei jeder Fließweg mit einem separaten, zugeordneten Radiator verbunden ist.
  • Die US 3,321,334 offenbart eine Brennstoffzelleneinheit, die ein Schein-Modul integriert, in welches ein flüssiger Brennstoff injiziert werden kann. Beim Betrieb der Vorrichtung wird Brennstoff, der durch das Schein-Modul 8 fließt, verdampft, wodurch eine Kühlwirkung auf umgebende Brennstoffzellenmodule erzeugt wird.
  • Die DE 42 08 609 offenbart einen Fahrzeugmotor, der einen Radiator integriert, der einen Teil eines geschlossenen Fluidflußweges bildet. Ein Bereich des geschlossenen Fluidflußweges wirkt als ein Wärmeaustauscher mit einem Ergänzungsreservoir, das flüssiges Elektrolyt enthält, welches in eine Einzelzellenelektrolyseeinheit innerhalb des Motors zu pumpen ist.
  • Es ist eine Aufgabe der vorliegenden Erfindung, eine verbesserte Elektrolyseapparatur bereitzustellen.
  • 1 ist ein schematisches Diagramm eines Elektrolysegeräts mit Schein-Zellen zum Erwärmen oder Kühlen des Elektrolysegeräts unter Verwendung von Flüssigkeit aus einem Fahrzeugradiator;
  • 2A, B, C und D sind schematische Diagramme von drei elektrischen Systemen zum Bereitstellen elektrischer Energie für das Elektrolysegerät.
  • Nun unter Bezugnahme auf 1 wird ein schematisches Diagramm eines Elektrolysegeräts 180 mit Schein-Zellen 182 zum Erwärmen oder Kühlen des Elektrolysegeräts unter Verwendung von Flüssigkeit aus einem Fahrzeugradiator 184 gezeigt. Die Schein-Zellen 182 können von Platten umfaßt sein unter Verwendung eines Durchgangs für das Radiatorfluid zwischen elektrolytischen Zellen 184, um Wärme zu absorbieren oder zum Elektrolysegerät zu liefern. Da Elektrolysegeräte am effizientesten bei erhöhten Temperaturen arbeiten, kann der Radiator verwendet werden, um das Elektrolysegerät unter Kaltwetterbedingungen zu erwärmen. Alternativ kann das Radiatorfluid verwendet werden, um das Elektrolysegerät nach einer ausgedehnten Verwendungsdauer zu kühlen.
  • Nun unter Bezugnahme auf 2A bis C gibt es vier mögliche Topologien für das Antreiben des Elektrolysegerätsystems 200. In 2A wird die Hauptquelle der Elektrolysegerätenergie unmittelbar aus der Fahrzeugbatterie 201 ebenso wie vom Generator 203 abgezogen. 2B eliminiert den elektrischen Abzug von der Batterie 201 durch Anordnen einer Diode 202 zwischen dem Generator 203 und der Batterie 201. Die Diode 202 ermöglicht einen Stromfluß vom Generator zur Batterie und anderen Fahrzeugladungen 205, stoppt jedoch den Stromfluß von der Batterie zum Elektrolysegerät 200. Der strombegrenzende Stromkreis 206 schützt das elektrische System vor Überlastungen, die durch das Elektrolysegerät abgezogen werden könnten, wenn sich der Elektrolysegerätwiderstand ändert. 2C ist mit einem Generator 204 mit einer zusätzlichen Wicklung gezeigt, in welcher der Magnetkreis Strom begrenzt auf das Elektrolysegerät 200 liefert. Diese zweite Spule würde ebenfalls erlauben, höhere Spannungen an das Elektrolysegerät 200 zu liefern, was ermöglicht, daß die Anzahl von Zellen innerhalb des Magazins erhöht werden kann. 2D ist ein System, bei dem der Fahrzeugwechselstrom vom Generator 207 abgezogen wird, bevor der Fahrzeugregulator 209 und ein separater Stromsteuerer/Regulator 208 elektrische Energie an das Elektrolysegerät 200 liefert. Diese Topologie ist in der Lage, die Elektrolysegerätladung stromseitig zu begrenzen und höhere Spannungen an das Elektrolysegerät zu liefern, während ein herkömmlicher Generator verwendet wird.
