Electrochemical Model of DMFC
The working principle of direct methanol fuel cell is shown in figure1[1]: At the anode, Methanol reacts with water to generate carbon dioxide, protons and electrons according to the anode reaction expressed by (1).
The overall reaction equation of the fuel cell is shown in the ( 3) Anode Reaction:: (1) Cathode Reaction: (2) The Overall Reaction: (3) B.
Figure7 Methanol fuel cell characteristics at different temperatures Figure 8: Methanol fuel cell characteristics at different concentrations According to the figure 8 under a certain output voltage, the fuel cell has the maximum output voltage when the concentration of methanol is 2.0 mol/ L−1.
A conclusion should be drawled that the concentration should not be more than 2 mol/ L−1 because a higher concentration can lead to lower fuel utilization efficiency and the lower Faradic efficiency[10].

Then the average weighted coefficient is taking into calculation in order to review the status of research target[1].
For instance, in the index weighted matrix X1=(x1,x2,x3,), x1+x2+x3=1.

C Result of simulation
Let initial distance between vessel and target be 3000m,target initial course be 0°,target initial relative bearing be 90° and target initial spped is 10kn.Two trajectories of underwater vehicle such as figure 1 show.Figure 1 show that the model established in this paper is usefulness and the underwater vehicle trajectory simulation is accuracy.
the underwater target usage anti-ship underwater vehicle, and from type 1 get the survival probability curve of ship with distance
For A type of lightweight shipborne underwater vehicle,suppose the fuse is impact action fuze,and suppose the destructive payload’s explosive equivalent is .By formula 2,obtain the value of is 1.
