Gas electrode

Japanese: 気体電極 - きたいでんきょく（英語表記）gas electrode

An electrode that contains gaseous substances among the substances involved in the electrode reaction. It is also called a gas electrode. It is often constructed so that a chemically inert metal electrode such as platinum or gold is inserted into a solution and the gas in question is passed over the electrode surface. Examples include the hydrogen electrode, oxygen electrode, and chlorine electrode. Pressure has a large effect on the equilibrium electrode potential of this electrode. A cell made by combining gas electrodes (for example, an acid-hydrogen fuel cell, an acid-alkali cell, etc.) is called a gas cell.

Japanese:

電極反応に関与する物質の中に気体状物質が含まれている電極。ガス電極ともいう。白金や金のような化学的に不活性な金属電極を溶液中に挿入して，電極面に問題の気体を通気するような構造になっていることが多い。水素電極，酸素電極，塩素電極などがその例である。この電極の平衡電極電位に対しては圧力の影響が大きい。気体電極を組み合わせてつくった電池(たとえば，酸水素燃料電池，酸アルカリ電池など)を気体電池gas cellという。
