    wobei das Basisteil so ausgebildet ist, dass es ein Produkt einer elektrochemischen Reaktion mit der Kathode, der Anode und einer Flüssigkeit ohne Pumpen in den Behälter transportiert.
  11. Das Verfahren nach Anspruch 10, ferner umfassend das Anbringen einer Strebe über dem Rand jedes der Kathode und der Anode, um den Abstand zwischen Anode und Kathode aufrechtzuerhalten.
  12. Das Verfahren nach Anspruch 11, ferner umfassend das Vorsehen von zwei oder vier Öffnungen in der Strebe.
  13. Eine Lösungserzeugungsvorrichtung, umfassend:
    ein Basisteil mit einer Anode und einer Kathode, die durch einen ersten Randabstandshalter beabstandet sind, um zu erzeugen,
    dadurch gekennzeichnet, dass:
    die Kathode zwei planare Abschnitte und einen an die beiden planaren Abschnitte befestigten Umschlingungsabschnitt umfasst; und
    wobei die Anode zwischen den beiden planaren Abschnitten der Kathode derart angeordnet ist, dass eine Oberkante der Anode ko-planar mit jeder Oberkante der beiden planaren Abschnitte der Kathode ist, wobei bei Anlegen eines elektrischen Stroms eine elektrochemische Reaktion mit einer Flüssigkeit erfolgt, um mindestens einen von Blasenstrom und Produktlösung zu erzeugen, wobei der erste und der zweite Randabstandshalter in Spalten zwischen der Umschlingungskathode und der Anode angeordnet sind, und
    ein fest mit dem Basisteil verbundener Behälter, der dazu ausgebildet ist, mindestens einen von Blasenstrom und Produktlösung aus dem Basisteil ohne Pumpen aufzunehmen.
  14. Die Vorrichtung nach Anspruch 13 weiter umfassend eine Stromquelle, die so konfiguriert ist, dass sie den Strom an die Anode und die Kathode anlegt, um die elektrochemische Reaktion zu erzeugen.
  15. Die Vorrichtung nach Anspruch 13 weiter umfassend eine Strebe, die über den Rand jeder der Kathode, der Anode und den Abstandshaltern angeordnet ist, und die so konfiguriert ist, dass sie den Abstand zwischen der Anode und der Kathode aufrechterhält.
  16. Die Vorrichtung nach Anspruch 13 weiter umfassend zwei oder vier Öffnungen in der Strebe.
  17. Die Vorrichtung nach Anspruch 13, wobei die Kathode so konfiguriert ist, dass sie die Anode an drei Seiten der Anode umschließt.
