TS-JRC/PTT/2021/CNP/0763  5  F1  The Equipment must have current/power continuous power measurement  devices particularly at :  - power supply,  - pump(s), and  - heater(s), etc.  F2  Gas/liquid separation devices per electrode to knock out remaining water  in the respective gas (oxygen and hydrogen).  F3  One oxygen sensor in the hydrogen exhaust gas stream and one hydrogen  sensor in the oxygen exhaust gas stream to trigger appropriate alarms and  actions in case of hazards.  F4  Hydrogen product gas flow meter and oxygen product gas flow meter (in  the low pressure line).  F5  Measurement devices for residual moisture in the hydrogen product gas  and the oxygen product gas (in the low pressure line).  F6  Separate safety purge using an inert (N2) gas for cathode and anode  lines.  F7  Water inlet consumption measurement device for both, anode and  cathode supply lines.  F8  De-ionised water (resistivity higher than 1 M Ω cm $^{-1}$) make-up system  connected to the local tap water supply.  F9  Variable flowrate water recirculation on both, anode and cathode supply  lines.  F10  Conductivy-meters on de-ionised water produced and in the recirculation  loops for both, anode and cathode lines.  F11  Pressure and temperature sensors on stack inlet and outlet water/gas  lines.  F12  10 additional inputs for analog signals for temperature measurement  devices K type thermocouples.
