Where is the power input? Where should I solder the cables that come from the fuel cell?

This silicon gasketing works well for me.

Excellent product and service. Thanks!

Great product, got it at a clearance price. Good cathode GDL for an electrolyzer.

Easy to use and assemble - was missing guide dowels when I received it, though.

I made a sealing using laser cutter. It is good.

This silicon is easy to cut using laser cutter. I successfully made a sealing.

輸送中のことだと思いますが、角が一部折れてました。 1週間で届き助かりました。 I think that it is during transport, but the corner was partly broken. I received it in a week and it was saved.

Good quality and fast gas permeation!

Very good. The background current is very low.

This filter was invaluable to the success of my fuel cell project!!!!

Great!

Hello, What is the standby current and power consumption of the board? What is the power conversion efficiency of the board at 3V and 5V? My fuel cell supplies about 1V~1.2V @10mA and open circuit voltage of the cell is about 1.5V. Is your DC/DC conversion board suitable for my cell? Please comment. Thanks. Regards, Kelvin

先日2枚購入し、基本性能に関しては問題なかったので追加で購入しました。 拡散層（集電体)が付随するとさらに良いです。 Purchased two the other day, with regard to the basic performance was purchased at an additional so there was no problem. It is even better when the diffusion layer (collector) is accompanied.
