notes - upgrade of base plate with pipes is successful. leakage test confirm that there is no leakage.(negative) - truexessory cell housing is build with electrolyte and in cold state leackage n2 was 0.08nl/min. - housing is rebuild with keracell 2 and connected electricly with test station. heating system had issues. after they are resolved it worked good. screenshot is in attach. after temperature 850 degree is reached safety gas is exchanged with pure h2.(h2=1nl/min; air=1nl/min) in dry mode cell did produce 1.165v as max (screenshot included). - after it humidification is activated and in that mode polarisation curve script is performed and it had results as given in screenshots. - after tests dry mode is established leakage test is performed with h2 and result is 0,06nl/min. - samling pipe heaters are tested and they work correctly. - on demand of customer co2 inlet is exchanged to be n2 and to be active regardless of temperature. - extra weight is mounted on holder of ceramic tube that surround contact rod. (picture bellow) purpose is to obtain the pressure on the housing and ensure low leakage. the on-site commissioning (osc) is done with remaining issues: - performance is not in accordance to the catalog. - leakage should not exist, and it is dependent on position and pressure on extra weight which is not in accordance with machine drawings. (improvisation) - platinum sensing wires should be extra isolated from contact with machine metal parts by putting ceramic perls on it
