“…It also describes the physicochemical phenomena that occur in those layers: gas diffusion in gas-filled pores, gas dissolution, dissolved gas diffusion in liquid-filled pores, ohmic conduction, and electrochemical reaction. We used a variation of the standard flooded agglomerate model [20][21][22][23][24][25][26][27][28][29][30] that has successfully described the diffusion, adsorption, and reaction phenomena in cathode and anode electrodes of hydrogen phosphoric acid fuel cells (PAFC) and polymer electrolyte fuel cells (PEMFC). The agglomerate model describes the electrode's catalyst layer as a collection of homogeneously distributed spherical agglomerates that are composed of carbon particles on which the electrocatalyst platinum particles are dispersed.…”

“…A tecnologia PAFC não consta dos planos de desenvolvimento do MCT, descrito no "Programa de Ciência, Tecnologia e Inovação para a Economia do Hidrogênio" (ProH2) 6 e nem é listada no "Roteiro para Estruturação da Economia do Hidrogênio no Brasil" 7 , desenvolvido sob a coordenação do MME. Entretanto, os resultados da pesquisa em célu-las PAFC realizada no Brasil 5,8,9 e no mundo [10][11][12][13][14][15][16][17][18] sugerem uma oportunidade tecnológica ao país. As células PAFC são duráveis, eficientes e podem ser fabricadas com custos competitivos.…”
