摘要:
This invention is to introduce a manufacturing method of fuel cell with integration of catalytic layer and micro sensors, which comprises following steps: manufacturing multi-hole silicon layer step, generating catalytic layer step, forming insulation layer step, integrating micro sensors step, and finalizing step. With the function of gas-diffusion layer in the multi-hole silicon wafer and multiple catalytic grains evenly spread over the inner walls of flow-way holes of the silicon wafer, a great catalytic layer can be formed effectively. Further, micro sensors properly are integrated. This invention's merits include simple structure and capabilities of simultaneously detecting temperature and humidity. Plus, it can heat up internally for a fuel cell.

A micro reactor having micro flow-guiding blocks includes a first gas flow channel, a second gas flow channel and a catalytic converter. There are several flow-guiding portions disposed on the first gas flow channel. Each flow-guiding portion has micro flow-guiding blocks, flow-impact recesses, and catalytic portions. The function of the micro flow-guiding block is to guide a flowing direction of the flow toward the catalytic portion on the flow-impact recess in order to increase a possibility of contacting and chemical reaction with the catalytic portion. So, guiding the flow direction toward the catalytic portion can increase the overall reaction efficiency. More turbulence is generated to obtain a better mixing. Plus, its structure is simple.

A light emitting diode (LED) device having a humidity sensor includes an LED portion, a humidity sensor and an external device. This LED portion has a base, a boning layer, an LED chip, and a sealing portion. The LED ship is adhered on the base by the bonding layer. The sealing portion encloses the LED chip. This humidity sensor has a transmission element. This humidity sensor is to detect humidity condition in the LED portion. The external device is to monitor humidity condition and variation in the LED portion. It can monitor the internal condition in the LED portion and is possible to detect both the temperature and humidity simultaneously.
