Abstract: An anion exchange branched co-polymer includes poly(aryl) and a branched compound and quinuclininuium side chains. The co-polymer may include xanthene or bibenzofuran. The anion exchange branched co-polymer may be more durable and have less creep and may have a higher ion exchange capacity (IEC) due to the structure and because some of the side chains may have multiple functional sites. The co-polymer may be cross-linked and may also include free radical inhibitors. The co-polymer may be incorporated into a support material and used in an anion exchange membrane or membrane electrode assembly.

Abstract: An autonomous underwater vehicle (AUV) including a hydrogen fuel cell is provided. The fuel cell control computer is a separate, stand-alone control system that interfaces with a vehicle control computer (VCC) to ensure safe operation of the fuel cell system. Relay logic for disabling the fuel cell enables the VCC to determine if the fuel cell has shut down, ensuring that the AUV system does not send power to the fuel cell system if there are unsafe conditions.
