1 Scope
This part specifies the terms and definitions used in proton exchange membrane fuel cell technology and its application fields.
This part is applicable to all types of proton exchange membrane fuel cells.
2 Physical objects and abstracts
2.1 Materials
2.1.1
hydrogen storage material
material that can absorb, store and release hydrogen when needed under certain conditions
2.1.2
electrocatalyst
a substance that accelerates the electrode reaction process without being consumed itself
2.1.3
non-precious metal catalyst
catalyst without any precious metal component
Note: The precious metal elements include osmium (Os), iridium (Ir), ruthenium (Ru), rhodium (Rh), platinum (Pt), palladium (Pd), gold (Au) and silver (Ag).
2.1.4
alloy catalyst
catalyst consisting of an alloy of two or more metals
2.1.5
core-shell catalyst
catalyst consisting of a core and a shell coated on the core
2.1.6
electrocatalyst support
substance, as a component of the electrode, used for supporting the electrocatalyst
2.1.7
electrolyte
liquid or solid substance containing mobile ions and thus having ionic conductivity
