Proton exchange membrane fuel cell-3
polymer solid exchange membrane
advantage
High conversion efficiency
Low temperature start (minus 30 degrees)
Effectively avoid corrosion problems and electrolyte leakage
Fast startup
Simple composition, compact structure, small weight and easy to carry
Since there are no working parts, the working noise is low and the service life is long.
shortcoming
high cost
High requirements for fuel purification
Waste heat can only be recovered in the form of hot water
The battery’s water and heat management system is complex
structure
membrane electrode
gas diffusion layer
bipolar plate
Current collector
Compression board
stack
Tail plate/seal
membrane electrode
catalyst
gas diffusion layer
Gas diffusion and current collection provide physical support to the proton exchange membrane.
proton exchanger
bipolar plate
Metal plate/graphite plate/composite plate
Mechanical support to provide flow channels for reaction materials and coolant
Separates oxidizing and reducing agents and manages generated water and heat
Sealing material
