Abstract

Development of reliable power sources is important for the sustainable, reliable and continuous operation of transportation, portable and various electric equipment in unmanned aircraft and field environment. Currently electric power delivery to such systems is mainly by battery packs. An alternative is to use fuel cells (FCs). FCs are electrochemical devices to convert chemical energy of fuels such as hydrogen and methanol to electricity. Methanol is an attractive fuel source because it is liquid at ambient temperature, has a much higher energy density than hydrogen and low reforming temperature (260-300 ^oC) due to the absence of C-C bonds. Thus, integration of methanol steam reformers (MSRs) with FCs makes it possible to continuously produce electricity in sustainable manner. The key challenge in such power system is the development of fuel cells which can be effectively operated at compatible temperature range of MSR, i.e., 260-300 ^oC in order to increase synergetic heat integration and system reliability, see Figure 1. Here, I will discuss the concept behind the design and development of new high temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) based on in situ formed phosphosilicate nanoclusters. The new HT-PEMFCs show high performance, high power output and high tolerance toward CO in H₂ fuels upto 12% at elevated temperatures of 200-250 ^oC. The results indicate that phosphoric acid doped polybenzimidazole (PA/PBI) membranes with in situ formed phosphosilicate nanocluster proton carriers show the technical feasibility in the development of integrated MSR-HT-PEMFCs for tomorrow’s sustainable power systems.
