Therefore, a precise quantitative technique is needed to monitor the real‐time dynamics of hydrogen evolution during Zn electrodeposition. In this study, we quantify hydrogen evolution using in situ electrochemical mass spectrometry (ECMS). This methodology enables us to determine a...

How many electrons does cobalt have? Cobalt Cobalt is a transition metal that is located in the first row of the transition metals. Its atomic mass is 58.933 g/mole and is used to make blue pigments. The largest mining operations for cobalt are in Central Africa. ...
How does hydrogen work in a car then? From its tank, the hydrogen is passed through an anode in a fuel-cell. The anode has a catalyst – usually platinum – which forces the hydrogen to split into protons and electrons. The protons get sucked across a ‘proton exchange membrane’ (PEM...
When atoms of hydrogen gas reach the catalyst, they split up into hydrogen ions (protons) and electrons (small black blobs). In case you're confused: hydrogen ions are simply hydrogen atoms with their electrons removed. Since they have only one proton and one electron to start with, a ...
