Claim 0:
1. A method for producing a porous ceramic electrode, said porous ceramic electrode comprising a layer deposited on a substrate, said layer being binder-free and having a porosity of more than 30 volume %, and less than 50 volume %, and pores having an average diameter of less than 50 nm, said method comprising the steps of:
(a) providing a colloidal suspension containing aggregates or agglomerates of nanoparticles of at least one material P having an average primary diameter D50 of less than or equal to 80 nm, wherein a distribution of the average primary diameter D50 is a monodispersed distribution, said aggregates or agglomerates having an average diameter between 80 nm and 300 nm,
(b) providing a substrate, wherein the substrate has a melting point above 600° C.,
(c) depositing a mesoporous electrode layer on said substrate by electrophoresis, by ink-jet, by doctor blade, by roll coating, by curtain coating or by dip-coating, from said colloidal suspension provided in step (a);
(d) drying the layer obtained in step (c), and
(e) consolidating the mesoporous electrode layer obtained in step (d) by pressing and/or heating.
