Motivation for the DuraDemo project§ In 2012-2013 TEKES FC programme supported industry
project Demo 2013
§ Durability demonstration of PEMFC technology was andstill is important for working machine industry
§ In Finnish sodium chlorate and chlor-alkali industry needfor large PEMFC systems for the use of by-producthydrogen – near term market
§ VTT had sufficient knowledge to demonstrate PEMFCsystems using by-product hydrogen from e.g. sodiumchlorate industry
NaCl + 3 H2O –> 2 NaClO3 + 3 H2 (and O2 + Cl2)2 H2O + 2 NaCl –> 2 NaOH + H2 + Cl2

Operational experiences ofPEMFC pilot plant using low grade hydrogen from sodium chlorate production process International Journal of Hydrogen energy. in press (Available online 8 October 2017)
• 5 stages of operation during 21 months
• Initial start-up was difficult due to watercondensation when stack were cold
• Remote start-up required a lot of extra work
• The main reliability issue was hydrogen supplyside components leading long down-time
• System control and system safety featureworked without any problems

By-product hydrogen production in Finlandand globally
§ Largest by-products sites now in Finland:§ Kemira Chemicals, Äetsä, Kuusankoski,
Joutseno§ Total > 18 000 ton/a (> 0,6 TWh)§ Significant increase of H2 from
Joutseno in 2018§ Eka Chemicals (Akzo Nobel), Oulu about
2000 ton/a§ 10000 ton/a would fuel 1000-2000 city buses
§ Globally§ By product H2 from chlorine production is
about 1 600 000 ton/a§ By product H2 from sodium chlorate
production is about 220 000 ton/a
Enough for 5-10 million fuelcell electric vehicles!

The quality of by-product hydrogen from sodiumchlorate production
§ According to thesis ofBraxenholm by-producthydrogen from sodiumchlorate production can not beused as FCEV fuel as it doesnot fulfil ISO 14687-2:2012requirements
§ Is this true?
§ What can be done to makethis hydrogen suitable asFCEV fuel?

Some conclusions
§ According to measurements hydrogen sodium chlorate productionfrom does not fulfil ISO 14687-2:2012 or ISO 14687-3:2014§ CO2 level is the main issue (as for H2 from chlor-alkali*)§ CO level is within limits most of the time§ N2, O2 and HCl level have not been measured
§ According to DuraDemo results hydrogen is pure enough that itdoes not cause additional degradation§ Indirect evidence for low HCl level
§ Options for getting this H2 available for FCEV fuel§ Additional purification – can be expensive§ Change CO2 limit in ISO 14687-2:2012 – will take 2-4 years§ Use H2 only in bus fleets – no issues if H2 quality measured

Some goals of durability testing in MARANDA project
§ Validate the system performance on a powertrain testbench and in a target marine vessel for a period ofminimum 6 months (4380 hours)
§ Fuel cell stack life should exceed 15,000 hours§ Same power – 10% lower stack voltage
§ Monitor quality of by-product hydrogen, including allrelevant impurities in ISO 14687-2:2012 standard
