    Hydrogen can also be used as a processing or alloying agent, and in the synthesis of battery electrodes, composite materials and alloys. The interaction of hydrogen with many metals, composites and alloys offers potential hydrogen storage systems. There is also a discussion of hydrogen sensors. (source: Nielsen Book Data). Hydrogen Definition. The electrochemical equivalent of a substance may be defined as the mass of the substance deposited to one of the electrodes when a current of 1 Ampere is passed for 1 Second, i.e. a quantity of electricity of one Coulomb is passed.
