2H₂O + 2e^- > H2 + 2OH^-

2OH^- > H₂O + 1/2 O₂ +2e^-

 

In the akalyne electrolyser the negative cathode looses electrons to the aqueous solution. Water breaks down into hydrogen and hydroxide ions. At the positive anode the electrons are absorbed by the negative hydroxide ions which are so oxidised to form water and oxygen.

 

在芳烃电解槽中，负极将电子释放到水溶液中。水分解成氢和氢氧根离子。在正阳极，电子被氢氧根负离子吸收，氢氧根离子被氧化形成水和氧。

CH₄ + H₂O > CO + 3H₂

 

Methane and water steam react in high temperature and in the presence of a catalyst to produce hydrogen and carbon monoxide. Heat needs to be added during this reaction (endothermic reaction)

 

甲烷和水蒸气在高温下和催化剂的存在下反应生成氢和一氧化碳。该反应（吸热反应）期间需要添加热量

C + H₂O > CO + H₂

 

Carbon (coal) reacts with water in high temperature to produce carbon monoxide and hydrogen. This is also an endothermic reaction.

 

碳（煤）在高温下与水反应生成一氧化碳和氢气。这也是吸热反应。

Hydrogen gas from the tank feeds to the positive terminal. Oxygen from the air comes down to the negative terminal. The positive terminal (red) is made of platinum, a precious metal catalyst designed to speed up the chemistry that happens in the fuel cell. When atoms of hydrogen gas reach the catalyst, they split up into hydrogen ions (protons) and electrons. The protons, being positively charged, are attracted to the negative terminal (blue) and travel through the electrolyte towards it. The electrolyte is a thin membrane in the middle made of a special polymer (plastic) film and only the protons can pass through it. The electrons power the electromotor which drives the car.

来自储罐的氢气进入正极。空气中的氧气向下流到负极端子。
正极（红色）由铂制成，铂是一种贵金属催化剂，旨在加速燃料电池中发生的化学反应。当氢气原子到达催化剂时，它们分裂成氢离子（质子）和电子。带正电的质子被吸引到负极（蓝色）并通过电解质流向负极。电解质是由特殊的聚合物（塑料）薄膜制成的中间薄膜，只有质子才能通过。电子为驱动汽车的电动机供电。
