“…The influences and mechanisms of the solvents mixed into catalyst ink were also investigated. The mixture of PFSA ionomer and organic solvents have three states: solution (ε > 10), colloid (3 < ε < 10) and precipitate (ε < 3), according to the dielectric constant ε of organic solvents, and the electrode prepared by a colloidal method usually shows better results [81]. Isopropyl alcohol (IPA) is the most commonly used solvent.…”

An advanced cathode design can improve the power performance and durability of proton exchange membrane fuel cells (PEMFCs), thus reducing the stack cost of fuel cell vehicles (FCVs). Recent studies on highly active Pt alloy catalysts, short-side-chain polyfluorinated sulfonic acid (PFSA) ionomer and 3D-ordered electrodes have imparted PEMFCs with boosted power density. To achieve the compacted stack target of 6 kW/L or above for the wide commercialization of FCVs, developing available cathodes for high-power-density operation is critical for the PEMFC. However, current developments still remain extremely challenging with respect to highly active and stable catalysts in practical operation, controlled distribution of ionomer on the catalyst surface for reducing catalyst poisoning and oxygen penetration losses and 3D (three-dimensional)-ordered catalyst layers with low Knudsen diffusion losses of oxygen molecular. This review paper focuses on impacts of the cathode development on automotive fuel cell systems and concludes design directions to provide the greatest benefit.

“…First, all over the world, many first-class teams gradually improve the fundamentally understanding of the nano-scale to milli scale FC electrode. For instance active layer carbon structure has recently proved to be of high importance [2,31,32]. Mesopores (4-7 nm) in the carbon aggregate are crucial.…”

“…They improve proton and oxygen transport phenomena, which impacts positively the FC efficiency at high current densities, while enhancing Pt-alloy particles catalyst activity and stability [31]. Moreover present disorder carbon structure shows increases the tortuosity of transport pathways reducing the potential performance of the electrode which improves FC performance both in terms of efficiency and life-time duration [32]. Designing an order microstructure of active layer could enhance the electrode performance by both favoring mass transport and achieving a homogeneous current density along the electrode surface [32].…”

The latest pre-production vehicles on the market show that the major technical challenges posed by integrating a fuel cell system (FCS) within a vehicle—compactness, safety, autonomy, reliability, cold starting—have been met. Regarding the ongoing maturity of fuel cell systems dedicated to road transport, the present article examines the advances still needed to move from a functional but niche product to a mainstream consumer product. It seeks to address difficulties not covered by more traditional innovation approaches. At least in long-distance heavy-duty vehicles, fuel cell vehicles (FCVs) are going to play a key role in the path to zero-emissions in one or two decades. Hence the present study also addresses the structuring elements of the complete chain: the latter includes the production, storage and distribution of hydrogen. Green hydrogen appears to be one of the potential uses of renewable energies. The greener the electricity is, the greater the advantage for hydrogen since it permits to economically store large energy quantities on seasonal rhythms. Moreover, natural hydrogen might also become an economic reality pushing the fuel cell vehicle to be a competitive and environmentally friendly alternative to the battery electric vehicle. Based on its own functional benefits for on board systems, hydrogen in combination with the fuel cell will achieve a large-scale use of hydrogen in road transport, as soon as renewable energies become more widespread. Its market will expand from large driving range and heavy load vehicles.

“…The heart of the fuel cell, specifically the proton exchange membrane fuel cell, is the membrane electrode assembly. It is a combination of the gas diffusion layers and catalysts for redox reactions on the anode and cathode with a proton exchange membrane in a sandwich structure [ 4 ]. Selection of the catalyst is crucial and mainly depends on the fuel used in the system.…”

Membrane electrode assemblies (MEAs) with palladium catalysts were successfully prepared by using a home-made manual pressing system with Nafion glue application that contributed to a decrease of additional energy consumption. The catalyst coated membranes were prepared with supported palladium on activated carbon (PdC) and unsupported palladium black (PdB) for comparison. The performance of passive, air breathing, functioning under ambient conditions and with low concentration (1 M) formate/formic acid fuel cell was evaluated. Based on polarization curves, the best result was obtained with carbon supported catalyst and HCOOK fuel, achieving 21.01 mW/mgPd. Still, constant current discharge with PdC showed an energy generation efficiency of 14% with HCOOH over 3% with HCOOK caused by lower potassium ion conductivity and its permeability through the proton exchange membrane. The faradic efficiency of conversion in the cell is equal to the overall energy efficiency and makes the cell self-sufficient.
