Conventional sliding mode controls (SMC) have always shown high robustness when applied to non‐linear systems. However, their applications are still limited due to their high‐frequency switching which could be a harmful phenomenon for different systems. As a solution, this paper proposes a high order SMC based drift algorithm. First, the algorithm is designed theoretically for a proton exchange membrane fuel cell system, where the stability study is proved with Lyapunov theory. Then, it was implemented in a commercial Heliocentris FC50 fuel cell system together with a power converter, a BK Precision 8500 programmable load, and a MicroLabBox dSpace DS1202. Comparative outcomes with the conventional SMC have shown the pros and cons of each scheme in terms of steady‐state oscillations, convergence speed, and robustness.
