We apply the conservation of energy and entropy balance equations to derive expressions for the maximum work of hydrogen-oxygen, hydrogen-air and methane-air fuel cells. We show that the theoretical efficiency of a fuel cell may exceed that of a Carnot engine operating between the same low and...

摘要: Solve the steady-state radial diffusion equation in a cylinder to calculate the flux through a tubular fuel cell, then set up the equations to calculate the oxygen concentration field inside the fuel cell and the total power produced....
fuel cell systems. Therefore, the hydrogen role in power generation and the available methods of sustainable hydrogen production are discussed briefly. The most emphasis is given to fuel cell systems which are introduced in some detail, with their classification and their modeling equations presented ...
In energy system modeling, mixed-integer linear programming (MILP) has emerged as the predominant optimization approach for the design and operation of multi-energy systems25,31,57,58. MILP stands out due to its ability to effectively solve systems of linear equations, while including nonlinearities...
various industrial and research applications. This is typically done by reacting hydrocarbons in the presence of steam at high temperatures, leading to the generation of carbon monoxide, carbon dioxide, and hydrogen in a process called steam methane reformation (SMR), as shown in Equations 1a and ...
The equations shown in Figure 1 describe the anode, cathode, and overall electrochemical reforming reactions, respectively, for ethanol under both acidic and alkaline conditions. Figure 1 also shows (a) the electrochemical processes which define both water and ethanol electrolysis and (b) demonstration...
