美国科学家开发出一种直接以生物质为原料的低温燃料电池。这种燃料电池只需借助太阳能或废热就能将稻草、锯末、藻类甚至有机肥料转化为电能,能量密度比基于纤维素的微生物燃料电池高出近100倍。相关论文已发表在《自然》杂志子刊《自然通讯》上。尽管以甲醇或氢驱动的低温燃料电池 American scientists have developed a low-temperature fuel cell that uses biomass directly. The fuel cell can convert rice straw, sawdust, algae, and even organic fertilizers into electricity with the help of solar energy or waste heat. The energy density is nearly 100 times higher than that of cellulose-based microbial fuel cells. The related papers have been published in Nature’s magazine “Natural News”. Although low temperature fuel cells are driven with methanol or hydrogen
