A commercially available fuel cell is too expensive, and cost reduction of it is required. Particularly, cost reduction of the separator is necessary. In this study, a new surface treatment has been applied to the separator of stainless steel, which is a candidate material for a low price separator, to improve electric conductivity. At first, we immersed stainless steel sheets in the mixture of alcohol and graphite powder to adhere graphite to the surface of stainless steel sheets uniformly. Then, the stainless steel was sandwiched with new stainless steel sheets and cold-rolled to adhere graphite powder strongly.

商用燃料电池价格过高，需要降低成本。特别是，降低分离器的成本是必要的。在本研究中，将一种新的表面处理方法应用于不锈钢分离器，不锈钢是低价格分离器的候选材料，以提高导电性。首先，我们将不锈钢片浸入酒精和石墨粉的混合物中，使石墨均匀地粘附在不锈钢片的表面。然后，将不锈钢夹在新的不锈钢板中，进行冷轧，使石墨粉粘附牢固。
