摘要:
A cellulose acylate film comprising at least one retardation raising agent having specific rod-like polarizability anisotropy or specific plane polarizability anisotropy, and specific distance between terminals of a molecule in a specific amount; a process for producing the same; and a polarizing plate and liquid crystal display using the same.
摘要:
A fuel cell (100) that generates power without discharging fuel gas includes: an electrolyte membrane (810); an anode (820) provided on one side of the electrolyte membrane; and a fuel-gas passage portion (840) provided on the outer side of the anode to form a fuel-gas supply passage through which fuel gas is supplied to the anode. The gas permeability of at least one of the electrolyte membrane and the anode in a thickness direction thereof varies from position to position in a direction the fuel-gas supply passage extends.
摘要:
The invention provides a fuel cell, which includes: an electrolyte; an anode that is placed on one side of the electrolyte and has a fuel gas consumption surface on which fuel gas is consumed; a cathode that is placed on the other side of the electrolyte; and a fuel gas passage having a first passaged for distributing fuel gas to previously set regions on the fuel gas supply surface, a second passage for supplying the distributed fuel gas to the regions, and a fuel gas supply portion for supplying fuel gas from the first passage to the second passage. The fuel cell consumes most of the supplied fuel gas in the regions on the fuel gas consumption surface. A fuel gas passage has a fuel gas leakage suppression portion for suppressing leakage of fuel gas between the first passage and the second passage.
摘要:
A fuel cell has: an electrolyte; an anode provided on one side of the electrolyte and having a fuel-gas consuming face at which fuel gas is consumed; a cathode provided on the other side of the electrolyte and having an oxidizing-gas consuming face at which oxidizing gas is consumed; and a fuel-gas passage portion forming a passage through which fuel gas is supplied to predetermined regions of the fuel-gas consuming face of the anode. The fuel cell has an operation mode in which almost the entire amount of the supplied fuel gas is consumed at the fuel-gas consuming face of the anode.
