質(zhì)子交換膜燃料電池不同流場的實驗研究與優(yōu)化
發(fā)布時間：2024-01-14 14:46
自21世紀以來,能源危機和環(huán)境污染日益嚴重。首先,隨著全球工業(yè)的快速發(fā)展,煤、石油等傳統(tǒng)燃料的消耗量不斷加大。傳統(tǒng)燃料燃燒將釋放大量的SO2、CO、CO2和NO3氣體,使得環(huán)境污染日益嚴重。全球氣候變化和溫室效應與CO2的排放息息相關,而其中超過一半的CO2排放來自化石燃料的燃燒。另外,化石燃料燃燒產(chǎn)生的SO2、NO3等有毒氣體還將帶來酸雨、臭氧層破壞以及海洋污染等一系列環(huán)境問題,危害社會的生存和發(fā)展。面對世界性的能源危機和環(huán)境污染,燃料電池作為一種清潔的能源轉(zhuǎn)換裝置,是當前很有前景的研究方向。燃料電池能通過電化學反應將燃料中的化學能直接并且連續(xù)地轉(zhuǎn)換成電能,這是繼水電、火電和核電之后的第四種發(fā)電方式。由于燃料不涉及過多的能量轉(zhuǎn)換過程,其轉(zhuǎn)換效率不受“卡諾循環(huán)”的限制,最高可達60%-80%,其實際使用效率是內(nèi)燃機的2-3倍。同時,由于燃料電池整個運行過程中只會產(chǎn)生水,因此可以有效緩解環(huán)境污染。除此之外,由于燃料電池內(nèi)部不涉及任何機械...
