Periodic Reporting for period 1 - low Pt loading FCCHP (Innovative fuel cell system for CHP application in Low Carbon Buildings)
Reporting period: 2016-07-01 to 2018-06-30
The overall objective of the project is to establish scientific and engineering merits for the development of new PEMFC systems with high performance, low cost and long durability using a novel Pt-nanowire electrode technology, and based on the results to develop a low Pt loading (<0.25mgPt /cm2) electrode processes and demonstrate high-performance PEMFC system in the mCHP for low-carbon residential applications.
Fig. 1 showed Pt-NWs growth in the carbon matrix that a Pt-NW electrode was made. Fig. 2 presents illustration of how a fuel cell stack is prepared from carbon powder to Pt-NW electrode. Different from conventional electrode from Pt/C catalyst, Pt-NW electrode is made of carbon powder + Pt precursor, not of Pt/C catalyst, hence all Pt-NWs accessible to Oxygen and are controllable in microstructure. The Pt-NW electrode is used to prepare Membrane Electrode Assemblies (MEA), and finally MEAs are integrated into a fuel cell stack.
