进一步的，所述燃料电池为反应温度为125°C至170°C高温质子交换膜燃料电池，所述重整制氢器与所述燃料电池之间不设置氢气提纯装置。
进一步的，所述甲醇水重整制氢燃料电池电动船舶还包括蓄电池，所述蓄电池与所述甲醇水重整制氢燃料电池发电系统共同为所述驱动电机提供电能。
进一步的，所述甲醇水重整制氢燃料电池电动船舶还包括配电箱，所述甲醇水重整制氢燃料电池发电系统、蓄电池与所述配电箱连接。
进一步的，所述甲醇水重整制氢燃料电池电动船舶还包括电机控制器，所述配电箱与所述电机控制器连接，所述电机控制器再与所述驱动电机连接。
本技术方案的工作原理是，甲醇水储存在所述甲醇水储存箱中，经所述重整制氢器产生富氢气体，富氢气体进入所述燃料电池发电，生成电能供所述驱动电机使用，进而驱动船舶行驶，由于甲醇水在常温常压为液态，可以常温常压储存，没有高压泄漏危险，并且储氢质量密度较高，以甲醇与水体积比为6/4为例，所配甲醇水储氢质量密度可以达到12wt%。
本发明的有益效果是：所述甲醇水重整制氢燃料电池电动船舶，避免搭载危险的高压氢气，转而搭载安全的甲醇水，并且同等质量情况下，可以搭载更多的氢气。
