BASF offers the state-of-the art anode electrode for high-temperature proton exchange membrane (HT-PEM) fuel cells and other relevant applications. This product is also known as Celteh P1100W Anode in the fuel cell industry and utilizes a woven carbon cloth with microporous layer as its gas diffusion layer. It is capable of operating in the temperature range of 120 and 180 °C and can tolerate large concentrations of carbon monoxide and reformate fuel streams used for such applications. This high performance anode electrode technology enables high temperature PEM fuel cell systems, PBI membrane based PEM fuel cell systems, PBI-copolymer membrane based fuel cell systems, and other high temperature PEM utilizing fuel cells to demonstrate exceptional performance with various fuels (pure H2, reformate, etc.) and long operational lifetimes.
This Celtec P1100W anode electrode has dimensions of 23.2 cm X 27.8 cm and sold as individually packaged electrode sheets. The anode catalyst is based on BASF's proprietary platinum alloy composition (also known as Pt-alloy) with a specialty carbon support and the platinum metal loading for this anode electrode is approximately ~1 mg/cm2.

Hydrogen/Air and Reformate/Air reactant based fuel cell performance of Celtec®-P MEAs are provided below.
One of the major benefit of the high temperature proton exchange membrane fuel cell technology is the capability of consuming the reformed hydrogen stream, it is essential that MEAs used in such electrochemical devices have excellent carbon monoxide tolerance. During the reformation reaction, there is a small amount of the carbon monoxide gas generated in the fuel stream exiting the reforming catalyst bed, and presence of carbon monoxide can impact the overall fuel cell performance. BASF Celtec®-P MEAs uses a proprietary anode and cathode catalysts in order to allow the Celtec®-P MEAs tolerate high levels of carbon monoxide compared to the other commercial high temperature PEMFC MEAs. The following graph provides an example performance curve for Celtec®-P MEAs at different CO concentrations as a function of temperature.
Conventional high temperature PEMFC devices would usually use a polybenzimidazole PBI) or a co-polymer of PBI membrane that is phosphoric acid doped after the production of the membrane. Such membrane activation and containment of the liquid acid inside the membrane result in acid leaching phenomenon. PEM fuel cells generate water as the main by-product at the cathode side and presence of water further impacts the acid leaching phenomenon with the conventional PBI membrane. Celtec®-P MEAs utilized an advance form of PBI membrane where the proprietary tetraamino monomer and dicarboxylic acid monomer are first reacted via polycondensation reaction in phosphoric acid and then a solution casting & hydrolysis step is carried out in order to obtain the Celtec®-P membrane. This sol-gel synthesis protocol allows the PBI membrane to attain a novel morphology where the phosphoric acid is contained inside the membrane more effectively and has less acid leaching issues compared to conventional PBI membranes. Laboratory test results showed that operational lifetimes of exceeding 20,000 hours can easily be achieved with Celtec®-P MEAs and Celtec®-P membranes. The following graph provides the robust performance of Celtec®-P MEA against different humidity conditions.
