AI Technical Summary
⚠Technical Problem
The existing fuel cell systems increase power consumption and deteriorate fuel efficiency when one fuel cell exceeds a certain temperature, leading to increased cooling capacity for adjacent cells, which is inefficient.
⚗Method used
A fuel cell system with multiple fuel cells, temperature detection units, a cooling medium supply unit, an energy storage device, and a control unit that adjusts cooling capacity and output limits based on detected temperatures to reduce power consumption.
🎯Benefits of technology
The system effectively cools the fuel cells while minimizing power consumption by optimizing cooling capacity and output limits, maintaining efficient operation.

Abstract
To efficiently cool the fuel cell while reducing power consumption. [Solution] The fuel cell system 100 includes a temperature sensor 52 that detects the temperature of each of the multiple fuel cells, a cooling device 41 having an electric pump that supplies a cooling medium to each of the multiple fuel cells, a battery 53, and a controller 102 that controls the output of the cooling device 41 and the multiple fuel cells and the charging and discharging of the battery 53 according to the temperature detected by the temperature sensor 52. When the temperature of the first fuel cell detected by the temperature sensor 52 exceeds a predetermined temperature, the controller 102 controls the cooling device 41 to cool the first fuel cell and the second fuel cell with a cooling capacity corresponding to the temperature of the second fuel cell, and also implements an output limit for the first fuel cell, and further discharges power from the battery 53 according to the output limit for the first fuel cell.
