Samples are cylindrical bodies with a diameter of (5.0 ± 0.5) mm, a height of 10.0 mm from the materials under study.
Minimal volumetric wear and energy intensity of wear has a material P4, from which it follows that it shows greater wear resistance, compared with other materials.

Hence, the investigation on cost/performance materials of bipolar plates has become a critical research issue, therefore we need to design a material which was suitable for fuell cell.
Materials and Methods Materials.
The composition of materials is shown in Table 1 as follows: Table 1.
One of requirement for bipolar plate materials is electrical conductivity.

A material on-line identification system based on THz time-domain spectroscopy using VC was developed in this paper.
As the prototype of material detection application, the material whose corresponding type characteristic spectrum has already existed in the database could be well identified.
Fig.2.The diagrammatic flow sheet of the material identification process In order to test the effectiveness of the on-line detection system, the time-domain spectroscopy of all the samples in different situations of tabletting is tested for verification, its on-line detection and identification results are shown as the Fig.3: Fig.3.THz-TDS online material detection Conclusion The experimental results show that, for the material whose corresponding type characteristic spectrum has already existed in the database, the system of material on-line detection in this paper can better realize the function of material identification and detection.
