Monolithic micro-direct methanol fuel cell in PDMS with microfluidic channel-integrated Nafion strip

Martinus Gijs, Meng Shen

We demonstrate a monolithic polymer electrolyte membrane fuel cell by integrating a narrow (200 mu m) Nafion strip in a molded polydimethylsiloxane (PDMS) structure. We propose two designs, based on two 200 mu m-wide and two 80 mu m-wide parallel microflui ...
