We claim:
1. A system (100) for controlling flow of hydrogen, the system (100) comprising:
a flow path (102) defined with an inlet (101) and an outlet (105), the inlet (101)
is fluidly connected to a source (201) and the outlet (105) is fluidly connected to a target
5 (202);
a regulator (103) fluidly connected to the flow path (102), and structured to
reduce mass flow rate and regulate pressure of the hydrogen received from the source
(201) to a first predetermined mass flow rate and a first predetermined pressure,
respectively; and
10 a flow control valve (104) fluidly connected to the flow path (102) and disposed
downstream to the regulator (103), the flow control valve (104) is structured to reduce
the mass flow rate of the hydrogen from the first predetermined mass flow rate to a
second predetermined mass flow rate for controlling flow of hydrogen.
2. The system (100) as claimed in claim 1, comprising a stopper valve (110) disposed in
15 the flow path, downstream to the flow control valve, the stopper valve is structured to
stop the flow of the hydrogen to the target (202).
3. The system (100) as claimed in claim 1, comprising a filter unit (120) disposed in the
flow path (102), downstream to the inlet (101), the filter unit (120) is configured to
filter the hydrogen entering the flow path (102) from the source (201).
20 4. The system (100) as claimed in claim 1, comprising a first temperature sensing device
(109) disposed in the flow path (102) downstream to the inlet (101), and is structured
to measure the temperature of the hydrogen received from the inlet (101).
5. The system (100) as claimed in claim 1, comprising a first pressure sensing device (108)
disposed in the flow path (102) downstream to the inlet (101), and is structured to
25 measure the pressure of the hydrogen received from the inlet (101).
6. The system (100) as claimed in claim 1, comprising a second temperature sensing
device (119) disposed in the flow path (102) do
