3 Terms and definitions
The terms and definitions defined in GB/T 19774 and GB/T 24499 and the
following ones apply to this document.
3.1
Pressure
The force acting vertically on a unit surface area of a vessel. In this Standard,
unless otherwise noted, pressure refers to gauge pressure.
3.2
Pressurized water electrolysis system for hydrogen production
A water electrolysis system for hydrogen production composed of a water
electrolyzer with a specified pressure and its auxiliary equipment, pipelines and
accessories, and enclosure, etc.
3.3
Alkaline water electrolysis system for hydrogen production
A water electrolysis system for hydrogen production composed of alkaline water
electrolyzer and its auxiliary equipment, pipelines and accessories, and
enclosure, etc.
3.4
b) It shall meet the requirements of various mechanical properties; and under
working conditions, maintain stable mechanical properties.
c) The chemical composition and metallographic structure of the selected
materials shall not cause or avoid hydrogen embrittlement.
d) The chemical composition and metallographic structure of the selected
materials shall not cause stress corrosion, cracking or oxygen corrosion
during operation.
5.2.1.4 The autoignition temperature of materials in contact with oxygen under
any conditions shall be 50 °C higher than the maximum acceptable operating
temperature.
5.2.2 Water electrolyzer
5.2.2.1 The water electrolyzer is the main equipment of the water electrolysis
system for hydrogen production. Its performance parameters will determine the
technical performance of the water electrolysis hydrogen production.
The performance parameters and structural design of the water electrolyzer
shall be based on the basic requirements of reducing the power consumption
per unit of hydrogen, reducing the manufacturing cost, and extending the
service life. The structural form of the water electrolyzer, the structure, coating
and material of the electrolysis cell and diaphragm shall be selected reasonably.
5.2.2.2 The hydrogen production capacity, purity, and impurity content of the
water electrolyzer shall be negotiated and determined in accordance with the
manufacturer’s enterprise standards and the user’s requirements.
5.2.2.3 The electrode material, coating or catalyst of the electrolysis cell of the
water electrolyzer shall be determined according to factors such as the
electrolyzer type/working parameters.
If a bipolar structure is used, the electrode is required to have good volume
conductivity. At the same time, the diaphragm shall be able to block the gas
exchange between the positive and negative compartments, to ensure the
purity of hydrogen and oxygen.
Titanium plate should be used as the plate substrate of the "electrolysis cell" in
the PEM water electrolyzer. Metal platinum can be used as a catalyst on the
negative electrode side. A ruthenium-iridium alloy or their oxide or mixture can
be used as a catalyst on the positive electrode side.
5.2.2.4 PEM water electrolyzer uses proton exchange membrane as electrolyte.
The proton exchange membrane shall have sufficient chemical stability and
a) The enclosure shall have sufficient strength, rigidity and durability, to
ensure the safety of all equipment and pipelines. The enclosure shall also
bear the stress and vibration of the hydrogen production system in the
process of transportation, installation and operation.
b) The enclosure shall be made of corrosion-resistant materials, such as
stainless steel plate or nickel-plated steel plate. Its thickness shall not be
less than 0.6 mm.
c) The insulating material of the enclosure shall be fixed by mechanical or
other appropriate methods. It shall be pre...
