We have executed the R&D on promotion of bio-hydrogen utilization. However, it would be difficult to reduce the cost and satisfy of the fuel specification. In this study, we focused on a mobile PEFC fueled by bio-H2 including H2S, and estimated several aspects from the viewpoint of LCA thinking. As a result, in the case of below 1.0 ppm H2S of bio-H2, the cell voltage drop was little seen. In the example of mobile phone with PEFC, the operation would not be affected by small contaminant. Also, the influence of resource depletion was discussed. For instance, the absorbents of Fe2O3 and ZnO can remove H2S effectively. However, in the environmental impact of resource depletion, the intensities are quite different. The intensity of Fe2O3 was approximately 0.6% in comparison to ZnO case.
