Abstract An indirect fuel cell concept is presented herein, where a palladium‐based membrane (either pure Pd with 25 μm thickness or 75 Ag alloy 10 thickness) used to separate the electrochemical compartment from catalysis compartment. In this system, hydrogen generated hydrogen‐rich molecule, such as formic acid, and selectively permeated through into it then converted electricity. way, in situ, overcoming issues associated storage presenting chemical an attractive feasible alternative potential application future micro‐ macro‐power devices for wide range of applications fuels.
