摘要： A method of depositing a thin gold coating on bipolar plate substrates for use in fuel cells includes depositing a gold coating onto at least one surface of the bipolar plate substrate followed by annealing the gold coating at a temperature between about 200° C. to 500° C. The annealed gold coating has a reduced porosity in comparison with a coating which has not been annealed, and provides improved corrosion resistance to the underlying metal comprising the bipolar plate.
