A fuel cell electric vehicle (FCEV) power control system reduces a power limitation in conditions such as uphill driving and/or high temperature environments. The FCEV power control system utilizes dynamic cooling detection logic and/or predictive convection. The FCEV power control system may be operated in accordance with a method of controlling power of a fuel cell including receiving a plurality of inputs including a heat output of the fuel cell, an ambient temperature, a temperature of a coolant of the fuel cell, and a time of operation of the fuel cell. The method may include calculating an accumulation of cooling from convection, an accumulation of heat generated from the fuel cell, and a cooling ratio. The method may include adjusting a maximum allowable current of the fuel cell based on the cooling ratio. Related apparatuses, systems, techniques and articles are also described.
