The invention relates to a fuel cell engine as well as a cold starting system and method. The cold starting system comprises an intercooler, a first three-way valve and a second three-way valve; the intercooler comprises a main body structure and a shell; the main body structure is arranged in the shell; a partition plate is arranged between the shell and the main body structure; a cavity between the shell and the main body structure is divided into a first chamber and a second chamber by the partition plate; an inlet and a first outlet of the first three-way valve are connected to an exhaust pipeline at the upstream of the intercooler, a second outlet of the first three-way valve communicates with the first chamber, and the first chamber is provided with an air outlet; and an inlet and a first outlet of the second three-way valve are connected to a cooling liquid pipeline at the downstream of the intercooler, a second outlet of the second three-way valve communicates with the second chamber, and the second chamber is provided with a liquid outlet. According to the system, the heat of waste gas exhausted by a cell stack and circulating cooling liquid flowing out of the intercooler can be fully utilized, the cold starting efficiency is improved, additional energy does not need to be consumed for auxiliary heating, and the fuel utilization rate and the engine efficiency are improved.
Description
Technical field [0001] The present invention relates to the field of fuel cells, and in particular, to a fuel cell engine and a cold start system and a method thereof. Background technique [0002] The low temperature and cooling ability of the fuel cell is an important technical indicator, and it is also a problem that restricts the fuel cell. At low temperatures, the PTC is first powered, and the PTC is heated by the circulating waterway, thereby enabling fuel The battery reaches its operating temperature, but in low temperatures, the performance and efficiency of the power battery are also very low, and some low temperatures will not be used, and additional energy is consumed. Inventive content [0003] The first object of the present invention is to provide a fuel cell engine cold start system to solve the problem of power cells that cannot work or perform poor performance during cold start, reduce additional energy consumption. [0004] A second object of the present invent...
