Embodiment Construction
[0016] Such as Figure 1-3 The shown semi-separated overflow fuel cell engine water tank is designed as a multifunctional semi-separated compensating water tank. The height difference of the humidification water tank is arranged, and an overflow partition 4 is provided between the two cavities of the cooling and replenishment water tank and the humidification water tank. The cooling water tank is provided with water inlet 1, return port 6, overflow port 7, and cooling water outlet 8, and the humidification water tank is provided with a humidification water outlet 9, and there is a separation bar between the water supply tank and the humidification water tank cavity 3.
[0017] The above semi-separated overflow fuel cell engine water tanks for vehicles are arranged according to different functions and height differences. The cavity bottom 10 of the cooling and replenishing water tank is higher than the cavity bottom 11 of the humidifying water tank, and is divided into two cav...

The invention discloses a semi-separation overflow type automobile-used fuel cell engine water tank. The cavities of a cooling water compensation water tank and a humidification water tank are merged and communicated; and the cooling water compensation water tank and the humidification water tank are arranged according to the actual design drop in level of a fuel cell engine system; an overflow intermediate separator is arranged between the two cavities of the cooling water compensation water tank and the humidification water tank; the recovered aqueous water generated during the operation ofthe fuel cell is used to complement the consumed water quantity of the two water tanks in turn; and the rest water is discharged via an overflow port. The semi-separation overflow type automobile fuel cell engine water tank solves the problems that currently the fuel cell engine system has uneven water consumption for humidification and cooling and heat dissipation; simultaneously the recovered generated water cannot be used to replenish the two separated water tanks correctly and sufficiently; the frequent judgment and the addition of deionized water are needed; and the whole fuel cell engine system has a water consumption balance problem. The semi-separation overflow type automobile-used fuel cell engine water tank not only can ensure the deionized water consumption of the two subsystems of the fuel cell engine system, namely the cooling circulating system and the medium cooling humidification system, but also can reduce the requirements on the supporting frame and fixation space.
Description
technical field [0001] The invention relates to a vehicle fuel cell engine water tank. Background technique [0002] During the use of fuel cell systems and fuel cell electric vehicles, it is necessary to use deionized water to cool the stack. Due to the particularity of the current fuel cell stack structure, there is also a certain amount of cooling water consumed during its cooling cycle; at the same time, for fuel cell Humidification requirements during operation require an additional humidification method to consume deionized water to humidify the oxidant-air and fuel-hydrogen of the fuel cell. The fuel cell also has the characteristic of generating water during the reaction process, and this part of the generated water can be recycled to the water tank to compensate for the consumption of deionized water in the water tank. [0003] The water tanks used in the existing fuel cell engines for vehicles generally adopt a split structure, that is, the water supply tank and t...
