The problem is that such technology works by forming bubbles of oxygen on the surface of electrodes deep within the molten ...

An oxygen electrode connected to a data logger can be used to measure the change in oxygen concentration.

By applying an electrode potential ... the active MXene surface facilitates the production of gaseous oxygen (O 2) by means of oxygen evolution—an important step in the formation of green ...

While hydrogen is fed to the anode, oxygen is fed to the cathode ... The greater the surface area of the electrodes, the greater the current. One of the great challenges automakers face is ...
