Self-Water-Removal and Voltage Behavior Improvement of Dead-Ended Proton Exchange Membrane Fuel Cell Stack at Steady-State and Dynamic Conditions

The proton exchange membrane fuel cell (PEMFC) demonstrates high commercial competitiveness due to its advantages: low operating temperature, power/mass ratio, fast response, no emission, and noise. Thermal water management remains a challenging issue for ensuring the cell’s performance at steady-state dynamic conditions. cathode moisture condensation uses semiconductor cooler effectively remove excess from PEMFCs reduce probability of flooding stack. stack’s voltage uniformity is an essential factor that affects lifetime PEMFC. This paper investigates response characteristics PEMFC stack under results show temperature 10°C during or transient operation can optimize performance. Compared conventional PEMFC, applying technology increases by 6% decreases up 30%. self-water-removal improves stack, which then increase durability.
