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