Abstract
Corrosion in manifolds and ducts in phosphoric acid fuel cells can be reduced by electroplating a chromium-fluorocarbon polymer composite coating onto the exposed metal surfaces. The chromium-fluorocarbon coating displays superior corrosion protection and improved adhesion after being subjected to a plurality of heating and cooling cycles. The improved corrosion protection enhances fuel cell operating reliability and allows the use of less expensive materials in the construction of the manifolds and ducts.
