一个完整的氧化还原反应方程式可以拆写成两个“半反应式”，一个是“氧化反应式”，一个是“还原反应式”。如2Fe³⁺ ＋ Cu ==2Fe²⁺＋Cu²⁺，可拆写为氧化反应式：Cu－2e^－ ==Cu²⁺，还原反应式：2Fe³⁺ ＋ 2e^－ ="=" 2Fe²⁺。并由此实现了化学能与电能的相互转化。据此，回答下列问题：

（1）将反应Zn ＋ 2H⁺ = Zn²⁺ ＋ H₂↑拆写为两个“半反应式”：其中，氧化反应为：                          。

（2）由题（1）反应，设计成原电池如图所示：

若电极a为Zn ，电极b可选择材料：         （只填一种）；电解质溶液甲是        ；电极b处的电极反应式：                   。

（3）由反应2H₂ + O₂ 2H₂O ，设计出以稀硫酸为电解质溶液的燃料电池，其电极反应式为：负极                       ，正极                       。
