Comparison between Fuel Cells and Heat Engines.
I. A Similar Approach in the Framework of Thermodynamics
with Finite Speed

Abstract:

The paper presents the main moments in the development of Thermodynamics with Finite Speed (TFS), the New Parameters introduced for description of Finite Speed Processes, the main formulae and tools, the main method for Speed, Temperature and other parameters of irreversible cycles optimization, called the Direct Method. We have observed that there is a similarity, between the quantitative approach of irreversible processes in Thermal Machines and those in Electrochemical Devices (Fuel Cells, Electrolysers and Batteries), based on expressing the First Law of Thermodynamics for irreversible processes with Finite Speed (combined with the Second Law) in a similar mathematical format in both fields(TM and ED). Methodologically, this is the starting point for the “unification” of TFS in the two domains developed independently: Engineering Thermodynamics and Electrochemistry. Keywords: irreversibility, Fuel Cell, Finite Speed Thermodynamics, Direct Method
