查询词典 black-headed

The anode catalyst for direct methanol fuel cell is Pt-W-Sn/C, and it is prepared through dispersing carbon black in distilled water, adding H2PtCl6, tungstate and stannate, stirring to make the metal salt and H2PtCl6 adsorbed fully; dropping reductant to reduce and deposite until complete reaction; washing with distilled water, filtering and drying to obtain black C carried sanitary Pt-W-Sn catalyst. The catalyst has excellent methanol catalyzing activity and low cost, and its use can lower the cost of direct methanol fuel cell greatly and raise the performance/cost ratio of the cell.

一种直接甲醇燃料电池阳极催化剂是Pt-W-Sn/C；其制备方法是将碳黑分散在蒸馏水中，然后加入H2PtCl6、钨酸盐和锡盐，搅拌使得金属盐与H2PtCl6被充分吸附；逐滴加入还原剂使之还原沉积，待反应完全后，用蒸馏水洗涤，过滤，然后于干燥箱中干燥，便得到黑色的C负载Pt-W-Sn三元催化剂；该催化剂具有很好的甲醇催化活性，价格低廉，可以大大降低直接甲醇燃料电池的成本，提高电池的性能价格比和市场竞争能力。
