Electrolysis is usually accompanied by gas evolution at one or both electrodes.

电解通常同时在一个或两个电极上析出气体。

Cation: an ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis.

阳离子：带有正电荷的一个或一群离子，特点为在电解中向阴极运动。

Clearly, though, the Bloom Box is still not a zero emissions tech and would only cut emissions by roughly 50% relative to the national average, unless it runs on landfill gas or biogas or hydrogen from electrolysis fueled by zero-carbon electricity (which would be much more expensive as you have to add cost of electrolysis unit, higher cost electricity, and about 30% conversion losses in electrolysis).
