Previous work made in the feld o membrane electrode assembly or uel cells is based on the optimization o bothstand alone materials: the catalytic electrode and the membrane. The assembly o these “separately optimized” mate-rials into a Membrane Electrode Assembly (MEA) is usually done by a hot press procedure. The MEA perormances,thereore, are usually not limited only by materials properties but also by the interace eect between the catalyticlayers and the membrane.
Context
All in one innovative concept
Scientifc and technological objectives
The SMAllinOne project introduces a “Smart All in One”uel cell corresponding to a thin flm protonic conduc-tive membrane with two catalytically unctionalizedsides. The AllinOne membrane is a novel composite ma-terial adapted or uel cell technologies as there is noboundary between the membrane and the electrodes.The innovative idea is to keep a same proton conductivebackbone or each layer, and to unctionalize it with em-bedded conductive catalyst particles or the electrodes.
The SMAllinOne project aims to build a smart unctionalized protonic membrane without interaces, keeping in minduture large scale initiatives.
The strategy is articulated around our main phases:
Synthesis o a proton conductive membrane viavacuum techniques: For the vacuum growth o this advanced proton conduc-tive membrane, new volatile chemical precursors will besynthesized, with protected acidic unctions. The chal-
lenge is thus to prevent the decomposition o the unc-tional groups during the thin flm membrane deposition.Various vacuum techniques will be investigated.
Structuring o a platinum catalytic network insidethe membrane: The potential o several vacuum methods (sputtering, co-deposition, atomized spray plasma deposition...) will beevaluated. Then the catalytic network will be integrated
in the proton conductive membrane.

1- The basic materials or the membrane and the catalyticelectrode will be developed separately using vacuumbased nanomaterial science technologies.
2- The selected components will be merged to generatea frst composite material without interaces: AllinOnemembrane.
3- Enhancement o the materials capabilities will bedone through nano-particulates addition to produce asecond generation o smart multi-unctionalized mem-brane: SMAllinOne.
4- This second generation will be optimized and testedor urther industrial implementation.

Smart Membraneor hydrogen energyconversion: All uel cellunctionalities in One Material
In the 1st phase, basic catalyticand membrane materials will beseparately set up to be used as pre-liminary building blocs.
1st main review point, (R1) atMonth 12: Basic material syn-thesis.
In the 3rd phase, advanced unctionalities such as electrical conductivity, tailored porosity, water retention and 3Dconormability will be developed on a single material. In parallel, the AllinOne concept will be optimized.
3rd main review point, (R3) at Month 24: Optimized AllinOne concept.
In the 4th phase, advanced unctionalities will be embedded in the AllinOne concept to produce a smart composite
membrane: SMAllinOne with enhanced electrochemical perormances.4th main review point, (R4) at Month 36: Proo o SMAllinOne concept GEN2.
In the 2nd phase, these prelimi-
nary building blocs will be mergedtogether to set up the concept baseline o the graded material. At month 18, this know-howwill be applied to optimized materials to produce a frst generation o composite membranematerial: the AllinOne concept.
2nd main review point, (R2) at Month 18: Proo o AllinOne concept GEN1.
SMAllinOne solution pathway and Workpackages
Adding smart unctionalities: The smart unctionalities target the enhancement o theelectrical conductivity, the water management, the mem-brane permeability and the porosity o the catalyticnetworks. To add such unctionalities, low cost nano-par-ticles will be introduced near the Pt nano-particles, hydro-philic domains and hydrogen getter will be added to themembrane and the porosity o the catalytic sides will be
adjusted or efcient uel supply.
3D conormability:3D conormability o the material will be studied or anincreased apparent active surace.
