This abstract first appeared for US patent application 18883019 titled 'METHOD FOR REDUCING TEMPERATURE PEAKS IN A FUEL CELL
Original Abstract Submitted
A method and system for reducing temperature peaks during start-up of a fuel cell with a two-phase cooling system, the method including setting a saturation pressure of a coolant, via a pressure controller, to a first saturation pressure such that a maximum temperature of a coolant induced by boiling delay is below a maximum operating temperature of the fuel cell, starting the fuel cell, in response to the maximum temperature of the coolant induced by boiling delay being exceeded, setting the saturation pressure of the coolant, via the pressure controller, to a second saturation pressure, wherein the second saturation pressure is higher than the first saturation pressure.
