Abstract
A fuel cell vehicle includes a fuel cell configured to discharge product water as a by-product of power generation, a condensate generation unit configured to generate condensate having a lower temperature than the product water, a radiator configured to dissipate heat from cooling water having cooled the fuel cell, a nozzle configured to allow at least one of the product water, the condensate, or mixed water obtained by mixing the product water and the condensate to flow to the radiator in response to a control signal, and a controller configured to generate the control signal in accordance with the degree of cooling required for the fuel cell.
Claims22
A fuel cell vehicle, comprising:
- a fuel cell including a cell stack configured to discharge product water as a by-product of power generation;
- a condensate generation unit configured to generate condensate having a lower temperature than the product water;
- a radiator configured to dissipate heat from cooling water having cooled the fuel cell;
- a nozzle configured to allow at least one of the product water, the condensate, or mixed water obtained by mixing the product water and the condensate to flow to the radiator in response to a control signal;
- and
- a controller configured to generate the control signal in accordance with a degree of cooling required for the fuel cell.
A method of cooling a fuel cell vehicle comprising a fuel cell configured to discharge product water as a by-product of power generation, a condensate generation unit configured to generate condensate having a lower temperature than the product water, and a radiator configured to dissipate heat from cooling water having cooled the fuel cell, the method comprising:
- providing mixed water obtained by mixing the product water and the condensate to an upper part and a lower part of the radiator based on a degree of cooling required for the fuel cell being less than a maximum degree;
- and
- providing the condensate to the upper part of the radiator and providing the mixed water to the lower part of the radiator based on the degree of cooling required for the fuel cell being a maximum degree.
