Hydrogen connection
The FCM-801 requires hydrogen to fuel the electro-chemical reaction. Connection
of the hydrogen fuel will be at the rear of the module. The connection type is a
G1/8 parallel BSP thread
with a face seal, it is recommended that this is then
connected via an appropriate mating connector.
The hydrogen pipework should be checked periodically for leaks. Particularly when
connectors have been remade, such as cylinder exchange or installation.
Hydrogen fuel physical requirements
The fuel cell requires fuel pressure to feed hydrogen into the cell. The inlet pressure
should be:
0.5 Bar.g to 0.7 Bar.g.
The FCM-801 will consume less than 16 slpm at rated power. It must be noted that
the flow will spike high during hydrogen purges which, if poorly regulated, can lead
to a pulse of low pressure. It is important that the fuel cell has the correct grade of
hydrogen (see Section 6.2 – Hydrogen fuel).
The hydrogen supply requires a shut-off valve, to allow the hydrogen to be isolated
at source, if required.
