An interconnect for a solid oxide fuel cell, its manufacturing method, and a solid oxide fuel cell including the same are provided.

Interconnect for a solid oxide fuel cell, its manufacturing method, and a solid oxide fuel cell

The present invention relates to an apparatus for evaluating a performance of a fuel cell stack, and more particularly, to an apparatus for evaluating a performance of a fuel cell stack, in which a guide unit and an arm are provided on an anode end plate and a cathode end plate, respectively, to minimize an inclination of the fuel cell stack caused by a shrinkage of a sealant.

Apparatus for evaluating performance of fuel cell stack

A fuel cell stack has a prevention dam formed outside an alignment pin, such that a sealing material, which has viscosity and fluidity at a sealing temperature of a fuel cell, may be prevented from coming into contact with and adhering to the alignment pin, and pressure applied from the outside may be uniformly applied to the fuel cell stack.

Fuel cell stack

Provided is a composition for manufacturing a polyester resin having a molar ratio of a diol compound to a dicarboxylic acid compound ranging from 1.05 to 1.4, in which the composition includes 5 ppm to 50 ppm of a phosphorous (P) compound (based on an amount of P), 10 ppm to 40 ppm of a cobalt (Co) compound (based on an amount of Co), 0.2 ppm to 20 ppm of a color enhancer, and 5 ppm to 25 ppm/3 ppm to 30 ppm of a titanium (Ti)-germanium (Ge) composite catalyst compound (based on an amount of Ti/Ge), based on weight percentage.
