Abstract
A vehicle includes at least one cooling circuit for cooling a fuel cell system. The cooling circuit includes at least one cooling heat exchanger, a cooling medium transportation device and a heat exchanger in a fuel cell stack of fuel cell system. Cooling heat exchanger is affected by motion-related air flow as cooling air. The cooling heat exchanger is constructed in at least two stages, which are arranged in such a way that they are serially flowed through, one after another, by motion-related airflow.
Claims12
A vehicle with at least one cooling circuit for cooling of a fuel cell system, wherein the cooling circuit comprises:
- a cooling heat exchanger that includes a first stage and a second stage arranged in such a way that the first and second stages are flowed through serially, one after another by motion-related airflow;
- a cooling medium transportation device;
- and
- a heat exchanger in a fuel cell stack of the fuel cell system,
- wherein the first and second stages of the cooling heat exchanger are flowed through serially, one after another, by a cooling medium flowing in cooling circuit,
- wherein the second stage is flowed through last by motion-related airflow and first by the cooling medium.
A vehicle with at least one cooling circuit for cooling of a fuel cell system, wherein the cooling circuit comprises:
- a cooling heat exchanger that includes a first stage and a second stage arranged in such a way that the first and second stages are flowed through serially, one after another by motion-related airflow;
- a cooling medium transportation device;
- a heat exchanger in a fuel cell stack of the fuel cell system;
- and
- a climate control device that includes at least one climate control cooling heat exchanger in order to cool a climate control medium used in the climate control device, wherein the climate control cooling heat exchanger is separate from the cooling circuit for fuel cell system.
