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.

Micro reactor having micro flow-guiding blocks

A manufacturing method of fuel cell having micro sensors and polymer layers is disclosed. It include the following steps of: (1) depositing first polymer layer step, (2) first lithographic processing step, (3) depositing chromium layer step, (4) depositing gold layer step, (5) removing first photo-resist layer step, (6) depositing second polymer layer step, (7) second lithographic processing step, (8) plasma etching step, (9) removing second photo-resist layer step, and (10) complete step. About this invention, the polymer layers can protect the micro sensors. The micro sensors can be installed at a specific location in the flow channel. The entire manufacturing cost is lowered.
