Water evacuation management
 
Fan is required.
Some residual water remains inside the MEA structure after standard cell was disassembled.
No fan required
Natural evacuation from absolutely hydrophobic gas diffusion cathode surface.
Altek’s PEMFC is simple: no fan, no control system for it.

Hydrogen purge
 
Periodically
Very sensitive to the hydrogen pressure regulation. Periodic purge is required.
None
Purge is not required. Once hydrogen parameters are set up there are no problems with fuel cell performance.
Altek’s hydrogen energy utilization is increased by 20%.

Observations
 
Bipolar plates and MEA’s components are very sensitive to the pressure between endplates.
Bipolar plates and MEA’s components are not subject to the pressure between endplates, because the current collectors are embedded into a GDE structure
Altek’s PEMFC design performance is improved by weight and volume decreased as a function of MEA design changed to 3 layers without required end plates with high pressure and bipolar plates
 
Difficult to save in storage for repeated test.*
No problem to store for repeated test, the MEA is reinforced by Ni mesh embedded into GDEs structure and baked together with PEM
This advantage allows us to get more durable PEMFC with increased lifetime and shelf life.
