1. Cost of manufacturing (labour, materials, utilities) of the m-CHP unit at current production levels (exclude monetary costs, e.g. overheads, profits, rebates, grants, VAT, insurances, taxes, land).
2. Lifetime (years) that the m-CHP unit, with its major components/parts being replaced, e.g stack, is able to operate until the End-of-Life.
3. Ratio of the time that the FC module was able to operate minus downtime divided by the time that was expected to operate. Downtime is the time that the FC is not able to operate-includes time for (un)scheduled maintenance, repairs, overhaul etc
4. Time that a maintained fuel cell stack is able to operate until End-of-Life criterion - as specified by the OEM.
5. Mean time between failure of the FC that render the system inoperable without maintenance or average time between successive failures leading to downtime: time that the FC is not able to operate includes (un)scheduled maintenance, repairs, overhaul etc
6. Electrical efficiency at rated capacity for the FC module as % of electrical output vs energetic content of fuel - Low Heating Value (LHV).
7. Thermal efficiency at rated capacity for the FC module as % of electrical output vs energetic content of fuel - LHV.
8. Operation and maintenance costs per kWh of electricity produced - Including running, overhaul, repair, maintenance labour costs and costs of stack replacement; excluding: fuel cost, insurances, taxes, etc.
9. Percent amount of hydrogen that can blended into the hydrocarbon feed (usually natural gas) allowing normal functioning of the fuel cell module.
10.Volume of fuel cell module as is available for installation in its basic configuration, in l/kWe.
