Abstract

The fuel cell has an anode (1) and a cathode (2) separated in a container (3) by a membrane (4), where the cell is excited by a pulse that is produced by laser, pressure or mechanical movement. Electrically conductive particles (6) are influenced by pulsating forces and are doped with catalysts. The conductive particles are drawn towards the anode or the cathode by applying a magnetic force (9), so that a direct contact between the conductive particles and the anode or the cathode is produced. Electrons flow over a consumer (10).

Es ist bekannt, dass die reagierenden Substanzen in Brennstoffzellen z. B. Gase, die nicht spontan an den Elektroden reagieren zu einer Passivierung der Elektroden und damit zu einer Verlangsamung und sogar zu einem Stillstand der gewünschten Reaktion führen.It It is known that the reacting substances in fuel cells z. As gases that do not react spontaneously at the electrodes to a Passivation of the electrodes and thus to a slowdown and even lead to a standstill of the desired reaction.

Um diesem unerwünschten Effekt entgegenzuwirken, werden verschiedene Maßnahmen angewandt z. B. der Einsatz von geeigneten Katalysatoren, erhöhter Systemdruck, unterschiedliche Elektrolyte, Temperaturen bis 1000°C, etc.Around this undesirable Counteract effect, various measures are applied z. B. the Use of suitable catalysts, increased system pressure, different Electrolytes, temperatures up to 1000 ° C, etc.

Der Betriebsaufwand bei den bekannten Systemen ist aber bis jetzt sehr hoch, sodass eine breite Anwendung der „Brennstoffzelle” noch nicht gegeben ist.Of the However, operating costs in the known systems is very much so far high, so that a broad application of the "fuel cell" is not yet given is.

Der Erfindung lag daher die Aufgabe zugrunde, die beschriebenen Nachteile dadurch zu vermeiden, dass der elektrochemische Prozeß zur Erzeugung von elektrischer Energie verbessert werden kann.Of the The invention was therefore based on the object, the disadvantages described thereby avoiding the electrochemical process for generating of electrical energy can be improved.

Die Erfindung betrifft das System einer galvanischen Zelle, im beschriebenen Fall ein Brennstoffzellensystem, bei dem der elektrochemische Prozess durch den Einbau von Partikeln, die durch Impulse angeregt werden, verbessert wird.The The invention relates to the system of a galvanic cell, described Case a fuel cell system in which the electrochemical process by the incorporation of particles stimulated by impulses, is improved.

Dazu wird ein System vorgeschlagen bei dem freie Partikel oder Teile (z. B. Lamellen) in der Zelle oder die Elektroden selbst durch äußere Impulse angeregt werden, wodurch aus mechanischen und elektrochemischen Gründen das System reaktiver wird.To a system is proposed in which free particles or parts (eg lamellae) in the cell or the electrodes themselves by external pulses be stimulated, resulting in mechanical and electrochemical establish the system becomes more reactive.
