In Situ-Grown Ultrathin Catalyst Layers for Improving both Proton Exchange Membrane Fuel Cell and Anion Exchange Membrane Fuel Cell Performances.

The mass transport and ion conductivity in the catalyst layer are important for fuel cell performances. Here, we report an in situ-grown ultrathin catalyst layer (UTCL) to reduce the oxygen mass transport and a surface ionomer-coated gas diffusion layer method to reduce the ion conducting resistance. A significantly reduced catalyst layer thickness (ca.

[Improvement of survival quality of the patients with hemodialysis treated with moxibustion for regulating spleen and stomach functions: multi-central randomized controlled study].

Objective: To discuss the impacts of moxibustion for regulating spleen and stomach function on the survival quality of the patients of end stage renal disease (ESRD) with maintenance hemodialysis (MHD).

Methods: One hundred and nine cases of uremia with MHD from 3 hemodialysis centers were randomized into an observation group (58 cases) and a control group (51 cases). The regular hemodialysis and conventional medication were used in the two groups.
