Abstract
A method for manufacturing a fuel cell includes the steps of: (1) providing a first bipolar plate and a second bipolar plate; (2) applying a first microseal to the first bipolar plate at a first metal bead seal region; (3) applying a first contaminant seal to the first microseal and the first metal bead seal region of the first bipolar plate, the first contaminant seal being configured to protect the first metal bead seal region from a debris piece; (4) assembling a UEA having a subgasket onto the first bipolar plate with a debris piece engaging with the first contaminant seal; and (5) compressing the second bipolar plate onto the first bipolar plate with the subgasket in-between while urging the first contaminant seal and the debris piece away from the first metal bead seal region. Alternatively, the first and second contaminant seals may be applied to the subgasket.
