Development of Compact NG Reformer for Residential PEMFCs |
| 초록 |
To apply PEMFCs(polymer electrolyte membrane fuel cells) as a residential cogeneration system(1-5 kW) requires a fuel processor to convert fuel into hydrogen. A compact and efficient reformer is necessary for this type of distributed power generation system. An integrated reformer of 2 kW class was developed. In order to reduce the size and improve the efficiency of reforming system, heat exchangers and each catalytic reactor were integrated with a suitable configuration, namely, dual pipe heat exchanging geometry. The total volume of the reformer including thermal insulation was 58 liters. The developed reformer system showed the highest efficiency of 73% as a HHV basis. The typical compositions of reformed gas from the exit of low temperature shift reactor were 73.6% H2, 21.7% CO2, 1.8% CO and 2.8% CH4. Further improvement of the thermal efficiency and integration of a preferential oxidation reactor as a carbon monoxide remover are on-going. |
