PLANAR HIGH-TEMPERATURE FUEL CELL

摘要

Fuel cells known from the prior art include ceramic-based high-temperature fuel cells in particular, wherein a cathodic ceramic substrate is the support for the fixed electrolytes and a cathode. According to the invention, a metal substrate (50) is provided as a support for the functional layers, wherein the metal substrate is porous for allowing reactants and reaction products to flow therethrough, and wherein the metal substrate and the functional layers are designed in planar fashion. A fuel cell system constructed of said fuel cells is suitable for operation at lower operating temperatures than previous SOFCs, in particular at temperatures of between 500 and 700°C. The novel fuel cells and associated system can be manufactured using comparatively simple metallurgical methods.
