摘要:
To improve stability and efficiency of a high-temperature solid-electrolyte fuel cell of planar multilayer design, it is proposed to increase the effective interface between the electrolyte layer and an electrode layer. This is achieved by a suitably treated surface of the electrolyte layer or by a porous and/or rough interlayer.
摘要:
A new high-temperature solid electrolyte fuel cell comprising an electrolyte layer between two electrode layers is obtainable by a process comprising the steps: (i) applying electrolyte particles in a screen printing paste on an unsintered electrolyte substrate and sintering the thus produced structure, (ii) depositing a nano-porous electrode thin layer by a sol-gel-process or an MOD-process on the structure obtained according to step (i) and thermal treatment of the thus coated structure. The fuel cell optionally has an electrolyte boundary layer on the structured screen printed electrolyte layer which is applied by an MOD process.
