Hydrogen is made in quantity by stream /methane reforming. Refineries currently make many tons per day with this process : it is used for hydrocracking , reforming ( making high octane fuels and plastics raw materials ) and other hydrotreating processes. Most of these processes consume H , but some actually produce H , but I no longer remember which is ...


The favored anode catalyst in a hydrogen fuel cell is platinum(1) or another platinum-group element (e.g. palladium). The catalyst is required in small quantities for an individual fuel cell but of course this demand scales up linearly with the number of fuel cells you want to produce. There is ongoing research into development of alternative anode ...
