H2O electrolysis using an anion conductive, solid polymer electrolyte is an attractive method for point-of-use H production Recent advances in catalysts and anion exchange membranes (AEM) have made alk. devices increasingly competitive with their acidic counterparts. However, less attention was paid to the anion conductive ionomers (ACI) used in the fabrication of electrodes for AEM electrolyzers. The ACI contributes to ion conduction between the catalyst and bulk electrolyte and serves as a binder for adhering the catalyst to the gas diffusion layer and AEM. Ionic conductivity, H2O uptake and ionomer swelling are critical properties for electrode performance. High ion exchange capacity (IEC) in the ionomer is desired for reduced electrode resistance, however, it can lead to excess H2O uptake (WU) and disruptive ACI swelling. Poly(norbornene)-based ionomers were synthesized, characterized and used to fabricate O evolving anodes for low-temperature AEM H2O electrolysis. The IEC of the ionomers (0 to 4.73 meq g-1) was adjusted by controlling the ratio of ion conducting to nonion conducting norbornene monomers in the ACI tetrablock copolymers. Low conductivity ionomers yield the best-performing O evolution electrodes, in the absence of ACI polymer crosslinking because they do not experience excessive H2O swelling. Light crosslinking within the anode ACI was used as a means to independently lower WU of the ionomer without compromising ionic conductivity This control over H2O swelling allows higher ionic conductivity within the ACI to be used in H2O-fed electrolyzer applications. Other methods of H2O management were compared including the use of hydrophobic additives and adjustment of the ionomer concentration in the electrode. The cell performance greatly benefits from a highly conductive ionomer in the O evolution reaction electrode if the WU is managed.
