  • Waste heat recovery system
    Patent number: 9331349
    Abstract: A waste heat recovery system includes a fuel cell, a coolant circulation flow passage, a first heat exchanger, a waste heat recovery flow passage, a second heat exchanger, an upstream end of the waste heat recovery flow passage, and a downstream end of the waste heat recovery flow passage. The coolant circulation flow passage includes a first coolant supply flow passage, a first coolant exhaust flow passage, and a first bypass flow passage. The upstream end is connected to at least one of an inlet coolant reservoir and the first coolant exhaust flow passage at a position downstream of a connection point between the first coolant exhaust flow passage and the first bypass flow passage. The downstream end is connected to at least one of the inlet coolant reservoir, an outlet coolant reservoir, and the first coolant supply flow passage.
