Start‐up from ‐25°C using catalytic combustion

Benefits Fast start‐up from very low temperatures

Challenges Stack must reach above‐freezing temperatures fast enough

to prevent ice formation from damaging MEA Reaction must be controlled to stop internal stack

temperature from getting too high and damaging MEA, but inlet and outlet temperature measurements cannot be used to control internal temperature

Normalised Direction of Coolant Flow

Catalyst Temperature for Different Start-ups

Coolant flow too low ( 78s start-up ) Coolant flow too high ( 68s start-up ) Optimised coolant flow ( 68s start-up )
