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.

市售的燃料电池太贵了，需要降低成本。特别是，必须降低分离器的成本。在这项研究中，已将新的表面处理应用于不锈钢的分离器，这是低价分离器的候选材料，以提高电导率。首先，我们将不锈钢板浸入酒精和石墨粉的混合物中，以将石墨粘附在不锈钢板的表面上。然后，不锈钢用新的不锈钢板夹住，并冷滚动以强烈粘附石墨粉。
