The process consists of two continuous stages carried out under inert, vacuum conditions. In the first stage, cold feedstock is fed into a preheating vacuum oven for ex-situ desulphurization. It is heated to a controlled temperature for a set time to break sulphur–sulphur and sulphur–carbon bonds
Current Proton Exchange Membranes (PEMs), especially Nafion, are costly and produced mainly by a single international supplier (DuPont/Chemours). This monopoly escalates the cost of fuel cells and electrolyzers and limits local manufacturing capacity in South Africa. Because PEMs are the major
