燃料电池电极反应的书写一直是同学们掌握不好的内容。从前面学的原电池方法进行书写会有一定的难度。以下是对这一内容的一点总结。燃料电池在高中阶段只要求掌握氢氧燃料电池和有机物燃料电池,在书写过程中按以下步骤会好掌握一点。即分三个步骤:1.写出总反应方程式;2.写正极反应式;3.再利用总反应减正极反应得到负极反应。一、总反应的书写其总反应和平时燃料燃烧的方程式大致相同,但要注意两点:第一就是反应条件不能写点燃,不要写反应条件。第二
Fuel cell electrode reaction writing has always been a bad grasp of the content of the students. From the previous study of the original battery method to write a certain degree of difficulty. The following is a summary of this content. Fuel cells in high school only require the master of hydrogen and oxygen fuel cells and organic fuel cells, in the writing process will be a good grasp of the following steps. That is divided into three steps: 1. Write the total reaction equation; 2. Write positive reaction; 3. Reuse the total reaction minus the cathode reaction to get the negative reaction. First, the total reaction of the reaction and the usual combustion of fuel combustion equation is roughly the same, but should pay attention to two points: First, the reaction conditions can not be written to write, do not write the reaction conditions. second
