Abstract
A method of assembling a fuel cell stack includes depositing a liquid seal material on an interconnect, pressing a fuel cell into the liquid seal material, and solidifying the liquid seal material after pressing the fuel cell into the liquid seal material. The seal material may also include a support portion or extensions which are configured to reduce an amount of compressive stress on corners of the fuel cell in the fuel cell stack.
