I bought this kit and I found little particles of water inside the fuel cell as if it had been used before, is it normal?

Hi Sebastian,All of our products are brand new. Please test and check if the fuel cell is working properly. Else, please contact Customer Service to start the RMA process.

What are the specs on the tubbing?

silicon tubing, 2mm inner, 4mm outer diameter

A PEM cell, tubing (~2 ft), 1 dc motor, a battery case with switch, a solar cell, 2 reservoirs for the O2 and the H2, 2 stands, wires a CD with instructions. very straight forward to follow.

If the fuel cell generates water as subproduct, How does water have to be removed from fuel cell for avoiding damage?

I haven't used mine in a while but I'm pretty sure it is a closed system. There is water at the beginning that is split into H and O with electrolysis and then that same H and O are combined back into water with the fuel cell. the first step requires electricity (solar panel) and the 2nd step makes electricity. Mine came with a small motor that ran in step 2. you don't have to remove excess water or add more water as this is all happening. it's a closed system.
