Fuel cell dosing control valve positioned in tube between pump and fuel cell

摘要: An assembly doses liquid reactants from a reservoir by means of pump through tube to PEM-fuel cell combustion system (PEM proton conducting electrolyte membrane). The novelty is that dosing control valve (7, 7a) arranged in the (5, 5a) between (4, 4a) and fuel (6, 6a). Further return (8, 8a) passes upstream 7a). A differential pressure regulator (9, 9a) regulates 6a) pre-determined value (delta p). second stage may be installed down flow first stage. If two separate systems are used for methanol water, common motor used.
