PEM Hydrogen Fuel Cell SystemProduct DescriptionWith the continuous
development of economy and society, the requirements for energy
cleanliness and high efficiency are becoming more and more
prominent.The energy structure is urgent. Hydrogen has been widely
used for a long time due to its wide source, high calorific value
and zero pollution.It is considered to be one of the clean energy
sources with the most development potential, and hydrogen energy
has also become an important way to adjust the energy
structure.Among them, hydrogen fuel cell stack is an important
application field of hydrogen energy.In terms of hydrogen
requirements for hydrogen fuel cell stacks, it is in line with the
hydrogen standard GB/T of general industrial industries.3634.2-2011
is very different. As shown in the figure below, GB/T 37244-2018
"Proton Exchange Membrane Fuel Cell GasVehicle Fuel Hydrogen", in
terms of hydrogen purity, 99.99% of high-purity hydrogen can meet
the requirements of 99.97% of fuel hydrogen.It should be noted that
CO≤0.2ppm is required.Product ParametersGB/T37244-2018 "Hydrogen

When the methane concentration exceeds 2 μmol/mol, the total
concentration of methane, argon and nitrogen is not allowed to
exceed 100 μmol/mol.The fuel cell power station adopts PEMFC fuel
cell technology, which directly converts hydrogen into electrical
energy through chemical reaction and simultaneously generates a
certain amount of heat energy, which gets rid of the limitation of
Carnot cycle of traditional combustion reaction, and has the
advantages of high power generation efficiency, small size,
quietness and zero carbon emission. , full operating conditions and
other advantages.The main advantages of fuel cell technology are as
follows:(1) High power generation efficiency:Fuel cell power
generation is not limited by the Carnot cycle. Theoretically, its
power generation efficiency can reach 85% ~ 90%, but due to the
limitations of various polarizations during operation, the current
power conversion efficiency of fuel cells is about 40% ~ 60%. If
the combined heat and power supply is realized, the total
utilization rate of fuel can be as high as 90% or more.(2) Small
environmental pollution:Because the fuel gas of the fuel cell must
be desulfurized before the reaction, and electricity is generated
according to the electrochemical principle, there is no
high-temperature combustion process, so almost no nitrogen and
sulfur oxides are emitted, which reduces the pollution to the
atmosphere.(3) Less radiationThe fuel cell has a simple structure,
less radiation and less loss. Even in the vicinity of a fuel cell
power plant of the 11MW class, the measured radiation is very
small.(4) High reliabilityWhen the load of the fuel cell changes,
it will respond quickly (10%-100% load change within 15s).
Regardless of overload operation above rated power or operation
below rated power, it can withstand with little change in
efficiency. Due to the highly reliable operation of fuel cells,
they can be used as various emergency power sources and
uninterruptible power sources.(5) Easy to constructThe fuel cell
has an assembled structure, which is convenient for installation
and maintenance, and does not require many auxiliary facilities.
The design and manufacture of fuel cell power plants are quite
convenient.Workshop EnvironmentCustomer Case Packaging &
