Abstract
Official abstract text for this publication.
A modeling method for designing a flow field of a fuel cell including a membrane electrode assembly including a catalyst layer and an electrolyte membrane, a gas diffusion layer, a flow field, and a bipolar plate includes modeling using a numerical model derived from a governing equation including a mass conservation equation of species, a fluid momentum in a porous media, and a modified Butler-Volmer's equation and outputting an oxygen diffusion characteristic in a catalyst layer from the modeling result.
First claim
Opening claim text (preview).
What is claimed is: 1 . A modeling method for designing a flow field of a fuel cell including a membrane electrode assembly including a catalyst layer and an electrolyte membrane, a gas diffusion layer, a flow field, and a bipolar plate, the modeling method comprising: modeling using a numerical model derived from a governing equation including a mass conservation equation of species, a fluid momentum in a porous media, and a modified Butler-Volmer's equation; and outputting an oxygen diffusion characteristic in a catalyst layer from the modeling result. 2 . The modeling method for designing a flow field of a fuel cell according to claim 1 , wherein the mass conservation equation of species i is expressed by the following Equations (1) to (5). ∂ ∂ t ( ρ ω i ) + ∇ · ( ρ ω i u ) = - ∇ ( · j ) L + R i ( 1 ) (Here, ρ is a density of a fluid, ω is a mass fraction, u is a velocity of a fluid, j L is a mass flux, and R is a source term consumed or produced by the reaction.) ∇ · j L + ρ ( u · ∇ ) ω i = R i ( 2 ) j L = - ( ρ D i m ∇ ω i + ρω i D i m ∇ M n M n - ρω i ∑ i M i M n D h
