Title: Engine and fuel cell system including first and second turbochargers

Abstract

An engine system includes an internal combustion engine, a fuel cell system, a first turbocharger and a second turbocharger. The internal combustion engine has an intake passage, and a first exhaust passage fluidly connected to the first set of combustion chambers. The first turbocharger has a first compressor and a first turbine. The second turbocharger has a second compressor and a second turbine, the second compressor connected in series with the first compressor, and the second turbine being in fluid communication with the second exhaust passage. The first and second turbines are connected in parallel such that the first turbine only receives exhaust flow from the fuel cell system, and the second turbine only receives exhaust flow from the internal combustion engine.
