Abstract: A vehicle includes a fuel cell system with a fuel cell arrangement and a fuel cell exhaust gas system receiving fuel cell exhaust gas from the fuel cell arrangement. The fuel cell exhaust gas system has a fuel cell exhaust gas outlet region for discharging fuel cell exhaust gas from the fuel cell exhaust gas system, and an ambient air heating arrangement for heating ambient air to be mixed with at least part of the fuel cell exhaust gas. The ambient air heating arrangement has an ambient air outlet region for discharging ambient air heated in the ambient air heating arrangement. The fuel cell exhaust gas outlet region is positioned downstream of the ambient air outlet region with respect to an ambient air flow direction of the heated ambient air discharged from the ambient air heating arrangement at the ambient air outlet region.

Abstract: The disclosure is directed to an exhaust gas heating unit for an exhaust gas system of an internal combustion engine. The exhaust gas heating unit includes at least one electrically conductive heating conductor element, wherein the at least one electrically conductive heating conductor element is configured from bent flat strip material. The exhaust gas system conducts exhaust gas defining an exhaust gas primary flow direction (H). The heating conductor element can have a plurality of broad sides arranged to be substantially parallel to the exhaust gas primary flow direction (H) and a plurality of end faces arranged substantially orthogonally to the exhaust gas primary flow direction (H).
