Fuel cell systems and methods for controlling the operation of components of the fuel cell system, which may include a fuel source and a fuel cell stack. In some examples, a fuel source is adapted to provide supply fuel to a fuel cell stack at a supply pressure. The fuel cell stack produces electric current at a production amperage. In some examples, a control system is adapted to control operation of the fuel cell stack based on a pressure detected at the fuel cell stack. In some examples, a target production amperage is determined based on the detected pressure, such that when electric current is produced at the target production amperage for the detected pressure, the fuel cell stack consumes a predetermined proportion of the supply fuel.

The present invention is directed generally to a nebulizer for the formation of micro-droplets from liquid medicaments for respiratory patient treatment, and more specifically, to a baffled nebulizer wherein a static baffle used to form an atomized medicament is proximal to a shied which responds to patient respiration force to oscillate from an aerosol flow occluding position to an aerosol flow open position. During inhalation, the shield moves into a first registration format to allow passage of the atomized medicament (nebula) to the patient. During exhalation / non-use, a biasing pressure maintains said shield in a second registration format such that the nebula is retarded from passing to the patient and is coalesced into macro-droplets which return to a supply reservoir for re-atomization. The present nebulizer design is particularly adaptable for controlling atomization in response to patient respiratory forces exceeding a defined threshold; allowing for opportunity to control inhalation airflow and enhanced therapy regimes.

The invention discloses an organic compound fertilizer with citrus pomace and a preparation method of the organic compound fertilizer and belongs to the technical field of preparation of organic fertilizers. The preparation method comprises the following steps of reducing the acidity of the citrus pomace by adopting microbial fermentation for deacidification, decomposing nondegradable components such as pectin and cellulose in the citrus pomace by adopting a compound-enzyme preparation, carrying out composting fermentation by microbial liquid inoculant, finally adding batched materials such as urea, monoammonium phosphate and potassium sulfate, and carrying out insect killing, sterilization, granulation, drying, cooling, sieving, coating and packaging to prepare the organic compound fertilizer with rich organic matter and the contents of N, P and K meeting the need of the optimal proportion for growth of citrus. The organic compound fertilizer and the preparation method disclosed by the invention have the advantages that deacidifying yeast is adopted to reduce the acidity of the citrus pomace and replace the existing method for adding quick lime to carry out deacidification, calcification and alkalization of soil are effectively prevented, the content of the compound fertilizer is more than 55%, the pH value is 6.5-8.5, the total contents of N, P and K are more than or equal to 8%, the water content is less than or equal to 20%, the contents of trace elements such as B, Zn and Mg are rich, and the other quality indexes are superior to national standard of organic fertilizer respectively.
