I know theoretically fuel cell efficiency decreases as temperature increases. But in practice it is vice versa. What is the reason of that? I couldn't find enough sources. Any kind of help is much appreciated.

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction. It consists of an anode, cathode, and an electrolyte that allows ions to pass between the two electrodes.
Fuel cell voltage refers to the electrical potential difference between the anode and cathode. It is a measure of the cell's ability to produce electricity and is typically measured in volts.
The main factors that affect fuel cell voltage include the type of fuel used, the type of electrolyte, the temperature, and the composition of the electrodes. Other factors such as humidity and pressure can also have an impact.
Fuel cell efficiency is a measure of how well a fuel cell converts chemical energy into electrical energy. It is typically expressed as a percentage and is affected by various factors such as temperature, fuel type, and operating conditions.
Fuel cell efficiency can be improved by using more efficient catalysts, optimizing operating conditions, and improving the design of the fuel cell components. Research and development efforts are ongoing to improve fuel cell efficiency and make it a more viable energy source.
