Abstract:
1. A conductive element for a fuel cell comprising; a first conductive sheet having a first surface that confronts a second surface of a second conductive sheet; wherein said first and said second surfaces are overlaid with an electrically conductive primer coating providing corrosion protection; wherein said first and said second coated surfaces are joined to one another at one or more contact regions by an electrically conductive adhesive which together with said primer provides a target bondline resistance across said first and said second sheets respectively which is lower than a comparative contact resistance of said adhesive without said primer, said electrically conductive adhesive having a glass transition temperature less than −20° C.; and said target bondline resistance is maintained for a time duration greater than a time duration during which said comparative contact resistance is maintained.
