... Electric generators Circuit theory Small‐scale direct methanol fuel cells (μ‐DMFCs) are considered nowadays as promising power sources for portable electronic devices, due to their simple structure, high‐energy density, and low‐operating temperature (Larmine and Dicks, 2003). Compared to Li‐ion...
