Fuel cell having a variable gas diffusion layer |
摘要 |
A fuel cell is described and which includes an ion exchange membrane having opposite anode and cathode sides; an electrode disposed adjacent to each of the anode and cathode sides; a gas diffusion layer which is located adjacent to each electrode and which defines a major surface and wherein at least one of the gas diffusion layers has a hydrophobicity which varies when measured in a direction which is substantially along the major surface, and which provides a substantially optimal hydration for the ion exchange membrane at fuel cell operational temperatures; an airflow is provided to the fuel cell and which is supplied in part to the cathode, and wherein the airflow further regulates the operational temperature of the fuel cell.
