Distributed Combined Heat and Power from Biogas with Optimized Heat Integrated Wall Reactor Reformer Integrated with Hybrid Cooled Metal Stack HT PEM Fuel Cell

AbstractVery few reformers have properties that make them useful for biogas CHP systems with fuel cells, and most fuel cell designs are not performing well when integrated with reformers for biogas. The reasons are several: Since biogas typically contains 30 – 40% CO2, any further dilution reduces the fuel cell efficiency to an unacceptable level. For good fuel cell efficiency the reformate must have high hydrogen content and low CO, and such a matched combination of fuel cell and reformer has to be of low complexity and low cost. Most reformer designs are simply too complex, too bulky and too expensive. Metacon has developed a Hybrid Cooled Metal Stack Technology (HCMST), that when integrated with the Helbio developed HIWAR reformer gives excellent performance, compact design and low cost. By matching and optimizing these two main parts of the complete energy system, and at the same time integrating the temperature control, heat management and water management of the total system. systems up to 1 MW that can be built, without negative effects such as noise, pollution, vibration and heavy maintenance
