Summary The conceptual design of an ammonia fuel processing unit (AFPU), which mainly consists of a heat‐exchanger type reactor and a hollow‐fiber membrane separator, is addressed. Through the theoretical modeling and simulations in gPROMS® environment, it is verified that the cocurrent‐flow annular reactor can carry out 99.5% ammonia conversion without external energy supply and the hollow‐fiber membrane separator produces 99.99% pure hydrogen for a proton exchange membrane (PEM) fuel cell. A combination of a PEM fuel cell power system, AFPU and a specific heat‐exchanger network framework is developed as a stand‐alone (off‐the‐grid) PEM fuel cell power generation system, where the optimal feed conditions are determined by solving a constrained optimization algorithm for maximizing the hydrogen yield of the AFPU.
