摘要： The present invention concerns a high power density solid oxide fuel cell having a cathode, electrolyte and graded porous anode. The graded porosity of the anode allows easy transport of fuel gases thereby minimizing concentration polarization. Power densities of about 1.8 W/cm2 at 800° C. and about 0.8 W/cm2 at about 650° C. have been achieved with graded porous anodes as thick as 0.75 mm. These fuel cells having a graded porous anode are more durable and mechanically reliable than those found in the art.

摘要： An improved electrode design for solid state devices, fuel cells, sensors and the like is made by incorporation of a porous layer of the electrolyte material over the dense electrolyte, and by the introduction of an electrocatalyst into the porous layer such that it is also continuous. The resulting electrode structure of dense electrolyte/porous electrolyte, continuous electrocatalyst and gas phase are present creating an enhanced three phase (TPB) length over that of conventional designs.
