Each of these atoms has a strong negative charge. This negative charge attracts the two H+ ions through the membrane, where they combine with an oxygen atom and two of the electrons from the external circuit to form a water molecule (H2O). This reaction in a single fuel cell produces ...
That is, the individual gas atoms include equal numbers of protons (positively charged particles in the atom's nucleus) and electrons. The negatively charged electrons perfectly balance the positively charged protons, so the atom has a net charge of zero. If you introduce many free electrons ...
The analysis of changes in the number of papers on GMF-related topics in the WoS and SCOPUS helped us to determine the degree of interest in the topic. However, we did not limit ourselves just to these two databases, but considered many other publications on the GMF and its impact on the...
