Abstract: A control system for an auto-stop/start vehicle includes a transmission load module, a target engine speed module, and an actuator control module. The transmission load module determines a load imposed on an engine through a transmission. The target engine speed module selectively determines a target engine speed during an engine startup event based on the load. The actuator control module controls at least one engine actuator based on the target engine speed during the engine startup event.
Abstract: A catalyst ink composition for a fuel cell electrode is provided. The catalyst ink composition includes: an ionomer; at least one solvent; a quantity of nanostructured thin film support cores; a catalyst formed from a precious metal, the catalyst coated onto the nanostructured thin film support cores; and a quantity of particles. The particles are configured to provide an electrode porosity that militates against excess water accumulation in the electrode formed from the ink composition upon a drying thereof. An electrode for a fuel cell and a method of fabricating the electrode with the catalyst ink composition are also provided.
