Transient numerical fluid analysis on gas distribution to anode cells of a fuel cell stack under start-up condition

Nihon Kikai Gakkai ronbunshu, 2015
Catalyst degradation on both the anode and cathode sides is one of the most critical problems caused by lack of hydrogen in each channel in the active area of a polymer electrolyte fuel cell.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

Advanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Analysis and optimization of stack temperature for proton exchange membrane fuel cell

Electrochemistry Communications
Voltage of the several cells near the end of the proton exchange membrane fuel cell stack is significantly lower than the average voltage of the stack. This is the so-called end effect phenomenon which is caused by the reduction in temperature of these ...
