1. A system for lubricating a hydrogen injector in a vehicle, the system comprising:
an extraction and separation device configured to collect at least a fraction of an exhaust gas of a hydrogen combustion engine and separate a water component from the collected fraction of the exhaust gas to provide liquid water and dried exhaust gas; and
a reactor connected to the extraction and separation device and configured to generate nitric acid from the liquid water and a nitrogen oxide content of the dried exhaust gas, wherein the hydrogen injector is connected to the reactor and configured to receive the generated nitric acid for lubrication.
