Abstract

The apparatus includes a reversible polymer electrolyte fuel cell (3) arranged in conjunction with a depressurized gas storage and the necessary conversion electronic devices. Both gases are stored separately in two fuel cells, without compression. The fuel cell is surrounded by an earthed metal vessel provided with a venting device. The fuel cell is reversible and is used for decomposition of water and energy and for transformation of gases. The apparatus is arranged as a closed system where the process water is reused.

Description

Der elektrische Strom, der von Photovoltaik, Windkraft, etc. bereitgestellt wird, wird in einem speziellen Wechselrichter (Teil Nr. 1 in Zeichnung Nr. 1), der nicht nur in Netzspannung 230 V/400 V 50 Hz umwandelt, sondern auch eine Niedertemperatur-Protonenaustauschmembran-Brennstoffzelle (Teil Nr. 3 in Zeichnung Nr. 1) beliefert. Diese dient zur „Wasserzerlegung”. Diese Einteilung ermöglicht, dass immer eine konstante Nennleistung zur Verfügung steht. Ein Überschuss an elektrischer Energie wird zur Elektrolyse in die Brennstoffzelle geleitet, die Wasserstoff und Sauerstoff in drucklose Gaszellen leitet und dort speichert. Bei unzureichender Stromzufuhr durch die Stromquelle (z. B. Photovoltaik) oder die Windturbine wird der Strom automatisch von der Brennstoffzelle bezogen, die den Wasserstoff und den Sauerstoff wieder in elektrische Energie umwandelt. Die beiden Gase Wasserstoff und Sauerstoff werden getrennt in drucklosen Gaszellen gespeichert. (Teil Nr. 1 in Zeichnung Nr. 2) Die Gaszellen sind von einer starren Hülle aus leifähigem Material umgeben. (Teil Nr. 2 in Zeichnung Nr. 2) Das Gas befindet sich in frei aufgehängten Gaszellen, die sich bei Gasüberschuss ausdehnen und bei Gasentnahme zusammenziehen. (Eingefärbte Felder in Zeichnung Nr. 2.) Die Gaszellen bestehen aus doppelwandigem elastischem Kunststoff. Zum Druckausgleich der Metallbehälter ist jeweils ein sehr feines Metallgitter über eine Öffnung in den Metallbehältern gespannt. (Teil Nr. 3 in Zeichnung Nr. 2). Die Tanks sind zusätzlich geerdet um elektrostatische Aufladung zu verhindern. Damit sinkt auch das Risiko einer Knallgasexplosion. Das bei der Reaktion der beiden Gase entstandene Wasser wird von der Brennstoffzelle zu einem separaten Tank geleitet. (Teil Nr. 9 Zeichnung Nr. 1). Dadurch steht es später wieder für die Elektrolyse bereit und bildet ein geschlossenes System.Electricity provided by photovoltaic, wind power, etc. is supplied in a special inverter (part no. 1 in drawing No. 1), which not only converts into mains voltage 230 V / 400 V 50 Hz, but also a low-temperature proton exchange membrane fuel cell (part no. 3 in drawing no. 1). This serves for "water separation". This classification enables a constant rated output to always be available. An excess of electrical energy is passed into the fuel cell for electrolysis, which conducts and stores hydrogen and oxygen in pressureless gas cells. If there is insufficient power from the power source (eg photovoltaic) or the wind turbine, the electricity is automatically sourced from the fuel cell, which converts the hydrogen and oxygen back to electrical energy. The two gases hydrogen and oxygen are stored separately in pressureless gas cells. (Part no. 1 in drawing no. 2) The gas cells are surrounded by a rigid shell of leifähigem material. (Part no. 2 in drawing no. 2) The gas is located in freely suspended gas cells, which expand in gas surplus and contract when gas is removed. (Colored fields in drawing no. 2.) The gas cells are made of double-walled elastic plastic. For pressure equalization of the metal container, a very fine metal mesh is stretched over an opening in the metal containers. (Part no. 3 in drawing no. 2). The tanks are also earthed to prevent electrostatic charging. This also reduces the risk of a blast gas explosion. The resulting in the reaction of the two gases water is passed from the fuel cell to a separate tank. (Part no. 9 Drawing no. 1). As a result, it is later ready for electrolysis and forms a closed system.
