A sealing assembly for a fuel cell system and a method of assembling a fuel cell system. The system is made up of numerous fluid-conveying plate assemblies stacked such that seals are placed between adjacent plates. Microseals are disposed on one or both of metal beads and subgaskets such that when fuel cells comprising such metal beads, microseals and gaskets are aligned and compressed into a housing of a fuel cell stack, the leakage impacts of any misalignment in the cells is reduced. In particular, variations in microseal design including geometric and material properties such as microseal aspect ratio, Poisson's Ratio and as-deposited shape may be tailored to provide optimum sealing between facing metal beads and subgaskets.
