3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 20042.1,
GB/T 24499, GB/T 24548 as well as the followings apply.
3.1 fuel cell hydrogen supply system
the device sum that supplies hydrogen for fuel cells, is related to hydrogen production,
storage and supply
3.2 hydrogen storage vessel
the container for containing hydrogen gas or hydrogen storage materials, excluding any
accessories placed or embedded inside or outside the container
3.3 hydrogen production material
the substances that produce hydrogen gas by themselves or with other substances
through physical or chemical processes
3.4 hydrogen production equipment
the device that produces hydrogen through a physical or chemical process of a
hydrogen-producing substance
NOTE: The device includes a filling port for the hydrogen-producing material.
4 System classification
The hydrogen supply system can be divided into:
- The hydrogen supply system for proton exchange membrane fuel cells, that stores
hydrogen as a gaseous element, is a system that stores hydrogen in a hydrogen
storage container and supplies hydrogen directly to a fuel cell. It includes the
following individual equipment or devices: hydrogen storage container, hydrogen
pipeline, stop valve, pressure reducing valve, pressure release device, heat
exchange device, monitoring device and other auxiliary devices, and so on. A
schematic diagram of the structure is shown in Figure 1. The pipe assembly in the
figure includes components, pipelines and joints that are in direct contact with
hydrogen or become part of the hydrogen supply system. It can be constructed
5.1.1 General
The fuel cell hydrogen supply system should meet the technical requirements for the
scale of hydrogen used in fuel cells and the quality of hydrogen and be reasonably
configured. The design, manufacture, inspection and acceptance of the single
equipment or devices, pipe fittings, materials used shall comply with the relevant
standards.
5.1.2 Vibration and Shock
The fuel cell hydrogen supply system should have a certain ability to resist vibration
and shock, so as to ensure that vibration and shock generated during normal use,
transportation or storage will not cause damage to various components of the hydrogen
supply system. The adverse effects of vibration and shock can be avoided by installing
anti-vibration devices, including vibration and shock generated by the unit and auxiliary
equipment in the system itself, as well as by the external environment.
After the hydrogen supply system has experienced adverse vibration and impact, it must
meet the requirements of 6.2.1 and 6.2.2. Precautions shall be in place to ensure the
safety of persons and property.
5.1.3 Material selection
The fuel cell hydrogen supply system should be compatible with hydrogen due to its
direct or indirect contact with hydrogen. The selected material should meet the
following requirements:
- It shall have necessary chemical stability under all conditions of use. Various forms
of chemical reactions will not occur in use to avoid the formation of hydrogen
pollution by these reactions. Hydrogen embrittlement, hydrogen corrosion, stress
corrosion and other forms of corrosion shall be greatly avoided. The hydrogen
embrittlement resistance of the selected materials can be tested with reference to
ISO 11114-4.
- It can adapt to the changes of the physical environment of the hydrogen supply
system, meet the requirements of various mechanical properties, and maintain
stable mechanical properties under the conditions of use.
- Non-metallic piping and related fitting materials meet the specified requirements
of the corresponding standards.
- The selected materials meet the requirements of the overall life expectancy of the
hydrogen supply system.
- When the materials used are known to be dangerous under certain conditions,
manufacturers should take various precautions and provide users with the
necessary information to minimize risks to personal safety and health.
5.1.4 Electrical system
5.1.4.1 All electrical components and wiring of the hydrogen supply system should
meet the requirements for safe use of hydrogen in terms of mechanical strength,
insulation and current carrying capacity. The wiring harness direction should be
arranged reasonably. The clamping should be good. Try to avoid friction with adjacent
parts. An overcurrent protection device should be installed in the line.
5.1.4.2 The materials of electrical components should be able to meet the usage
environment of the hydrogen supply system. When selecting an electr...
