Abstract: |
|
Fuel cells can be considered as one of the most potential green power due to their high power density, high energy efficiency, low operation temperature, environmental friendliness etc. As a key component of alkaline fuel cells, anion exchange membranes (AEMs) take the function of separating fuels and oxidant and transporting the hydroxide ion from the cathode to the anode. AEMs were developed rapidly in the recent several decades, but still at an outset stage. The critical issue associated with AEMs is insufficient ionic conductivity under alkaline conditions. In this paper, the influence factors on the ionic conductivity of AEMs were summarized. Some research progresses on the structure control for optimizing the ionic conductivity were described and the relationship between microphase separation and ionic conductivity were also analyzed. Finally, the problems existed in the present research and the new trend in the future was pointed out. |
