Abstract
To produce reference electrodes for galvanic cells having solid electrolytes, comprising metal oxides or/and double oxides, at least one oxide or double oxide is prepared as a hydrosol or organosol and applied in liquid form to the electrolyte to form a solid film. Preferably, a double oxide Me1xMe2yOz and (i) a metal oxide Me2mOn or (ii) a double oxide Me1aMe2bOc with a lower Me1 content are present in the reference electrode material.
Claims4
A method for producing a reference electrode for galvanic cells having solid electrolytes containing at least one of a metal oxide or double oxide, the method comprising the steps of:
- (a) preparing a hydrosol or organosol from at least one oxide or double oxide;
- (b) applying the hydrosol or organosol of step (a) in liquid form to said electrolyte;
- and
- (c) forming a solid film of the hydrosol or organosol on said electrolyte,
- thereby providing an intimate contact of the at least one oxide or double oxide and the electrolyte without the addition of a binder to the hydrosol or organosol of step (a).
