  "textContent": "A fuel cell system includes a plurality of fuel cell units each including a fuel cell, a fuel cell cooling system having a heat exchanger that exchanges heat between a primary-side coolant, and a secondary-side coolant flowing through the fuel cell, and a coolant pump that adjusts the flow rate of the secondary-side coolant, and a controller that controls the fuel cell, a cooling device, and a cooling system that supplies the primary-side coolant from the cooling device to each fuel cell unit. During stop of operation of the fuel cell system, the cooling device supplies the primary-side coolant having a temperature equal to or higher than a predetermined temperature to each fuel cell unit, and the controller activates the coolant pump to cause the secondary-side coolant to flow through the heat exchanger, in one or more fuel cell units in which the fuel cell has a possibility of freezing.",
