碩論剛好是做氧氣析出和氧氣還原催化相關的來發表一下拙見
這邊有人會問氧氣析出和氧氣還原和氫燃料電池有什麼關係?
簡單解釋電解水產氫和氫氧化成水這兩個反應的速率決定步驟就是氧氣析出和氧氣還原
因此要開發高效率的電解水產氫和燃料電池催化劑就要從氧氣析出和氧氣還原催化劑下手
留言看起來很多人認為耗電電解水產氫再拿氫發電是件很愚蠢的事情
其實是因為把氫能本身誤會成一種綠能了
事實上氫氣是一種類似於水力的儲能媒介
離峰用電時間會將水抽到高處利用重力位能的形式儲存 待尖峰用電時間再利用水力發電
氫能理想情況也是將綠能如太陽能或風力產生的電能電解成氫氣形式來儲存後運送及發電
然而現今氫燃料電池使用的氫氣仍以開採為主要來源
一部分原因是因為受限於電解水產氫的效率過低和催化劑成本太高壽命太低(貴金屬為主)
再來就是氫氣的儲存和運送成本也過高(對電力取得和運送容易的地區來說)
氫氣是在發電端就將電能轉換成化學能儲存 鋰電池則是在使用端才將電能轉換成化學能
結論
以現今利用更耗能或是開採的方式產氫來儲能用作汽車動力來源
相比使用鋰電池來說只能說是可笑至極
