Some of this carbon dioxide is absorbed by ocean water, altering the proportion of hydrogen and carbonate ions, and making the water more acidic.
一些二氧化碳会被海水吸收，改变海水中氢和碳酸盐离子的比例，使得海水酸化。

Ocean acidification has further chemical implications: more hydrogen ions mean more bicarbonate ions, and fewer carbonate ions.
海洋酸化还会进一步引起连锁化学反应：更多的氢离子意味着碳酸氢根离子多了，而碳酸根离子少了。

Molten carbonate fuel cell (MCFC) is an energy conversion device that converts chemical energy into electricity by oxidation of hydrogen or fossil fuels.
