Abstract
According to the present disclosure, a pattern comprising protrusions and grooves is formed on all layers in a laminate laminating a composition layer for preparing an electrolyte; and at least one of a composition layer for preparing a fuel electrode and a composition layer for preparing an air electrode on the composition layer for preparing an electrolyte, which leads to advantages of saving time and costs in terms of process by carrying out sintering and pattern forming at once, while improving cell efficiency by increasing a surface area of the electrolyte layer.
