Anion exchange membrane fuel cells (AEMFCs) are important alternatives to proton (PEMFCs). However, AEMFCs involve slow hydrogen oxidation reaction (HOR) on the anode. Catalysts improve HOR were developed by control of ruthenium nanoparticle size, alloying with iridium, and surface modification metal nanoparticles, resulting in enhanced catalytic activity optimizing binding energy bifunctionali...

Fuel cells output power depends on the operating conditions, including cell temperature, oxygen pressure, hydrogen tempureter . In each particular condition, there is only one unique point for a fuel system with maximum output. Thus, tracking (MPPT) controller needed to increase efficiency of PEMFC systems. this paper an efficient method fuzzy logic proposed MPPT proton exchange membrane (PEM) ...

Hybrid polymer electrolyte fuel cells combine a proton exchange membrane PEM and anion exchange membrane AEM and exhibit unique advantages. The electrochemical performance and current limitations of a hybrid cell with an alkaline electrode fabricated on a Nafion membrane was characterized at 70°C as a function of relative humidity. To separate the individual characteristics of the AEM anode and...
