The air inlet 102 is confronted with the first accommodation portion 103 and tightly adjacent to the first accommodation portion 103. Another sidewall of the case 100 is configured with the fuel outlet 105 and the product inlet 106, and the product inlet 106 is connected with the second accommodation portion 107. The upper right location of the second accommodation portion 107 is configured with a hole 108, which is located at the intersection of the second accommodation portion 107 and the fourth channel 117. Both ends of the hole 108 are connected with the ends of the second accommodation portion 107 and the fourth channel 117, respectively. The other end of the fourth channel 117 is Connected with the first accommoion portion 103.
100101 The pressure relief valve 22 is placed in the hole 108. When the internal pressure of the second accomodjon portion 107 is too large, the gas with the second accomnodatjon portion 107 will flow into the first accommodation portion 103 through the pressure relief valve 22 and the fourth channel 117.
100111 The fuel inlet 101 is connected with the end of the first channel 110. The other end of the first channel 110 is connected with the second accommodation portion 107, and the channel space at this end is Configured with a first one-way valve 112, and the one-way valve 112 oniy allows the fluid flowing to the second accommodation portion 107.
100121 The end of the second channel Ill is connected with the second accommodation portion 107, and the channel space at this end is configured with a density detector 113.
The other end of the second channel 111 is connected with the inlet of the second pump 500 through piping. The embedded density detector 113 is used to measure the density of the fuel toward the fuel cell stack 600. The measured fuel density could be provided for the control circuit (not shown). The density detector 113 used in the present invention could directly employ the conventiona' devices.
[00131 The end of the third channel 115 is connected with the first accommodation portion 103. The other end of the third channel 115 is connected with the inlet of the second one-way valve 116. The outlet of the second one-way valve 116 is connected with the second channel 111. The second one-way valve 116 only allows the fluid flowing to the second channel 111.

Moreover, the location on the first sheet 50 corresponding to the second channel 111 is configured with two joint pipes S3a, 53b, and the joint pipes 53a, 53b penetrate through the first sheet 50 and are spaced with a small distance. And, the lower surface of the first sheet 50 located between the two joint pipes 53a, 53b is configured with a block 52. The block 52 would extend to the second channel 111, and block the connection of the second channel 111. Both ends of the external density detector 54 are connected with the two joint pipes, respectively. When the fuel of the second channel 111 are flowing through the block 52, due to the blocked effect by the block 52, the fuel would turn and flow to the joint pipe 53a, the external density detector 54, the joint pipe 53b, and then into the second channel 111. The external density detector 54 is used to measure the density of the fuel flowing to the fuel cell stack 600. The measured fuel density could be provided for the control circuit (not shown). The exrternal density detector 54 used in the present invention could directly employ the conventional devices.
S [0019J In order for the operational convenience of connection of the pipe of the second pump 500 with the multi-functional fuel mixing tank I according to the present invention, both locations, that is the end of the first sheet 50 corresponding to the second channel Ill and the end of the fuel outlet 105, are configured with twojoint pipes Sla, 51b, respectively.
The two joint pipes 51 a, 51 b penetrate through the first sheet.
