√Bipolar plate is the main component of fuel cell, and graphite bipolar plate is used at present.
√Stainless steel bipolar plate can be used as an alternative, this material is not sensitive to vibration, has absolute air tightness, reasonable production cost, and is much thinner than graphite bipolar plate.
√HCVAC has been successfully used to deposit carbon films on stainless steel bipolar plates.
√The characteristics of carbon coating and gold coating are similar in ICR, adhesion and corrosion resistance.
